In one sentence, describe what the following article is about: Both will help keep you warm as the weather starts to grow colder. Keep in mind, however, that skinny jeans look best tucked into a pair of jeans, while boot cut jeans look better when placed over the boots. Here are some more ideas: Pair skinny jeans with some black or brown knee-high riding boots. A white shirt worn under a plaid button-up shirt will complete the outfit. Wear some boot cut jeans over a pair of work boots; avoid tucking them into the boots, or you will create too much bulk. Pair this with a long-sleeved, scoop-necked shirt. If you can't part with your skirts and dresses for a season, then wear them with a pair of dark-colored tights or leggings and a pair of boots for a quick, chic look. Just because fall brings cooler weather does not mean that you have to put your favorite tank top of short-sleeved shirt away. You can still keep warm while wearing your favorite shirt by pairing it with a chic, fitted suit jacket or light cardigan. You can also pair it with a light-weight sweat or hoodie. Here are some more ideas: Cardigans come in both short and long lengths. Consider wearing a long cardigan un-buttoned, and securing it around your waist with a wide belt. A pair of skinny jeans and tall boots will complete the look. Try a tweed or corduroy jacket. The textures will add some contrast to your outfit. If you live in a cooler area, keep warm by wearing longer coats or a trench coat. If you live in a warmer area, then try to find a jacket without a lining. You can keep warm on cool mornings with a tank top worn under a long-sleeved shirt or cardigan. As the day grows warmer, you can take the cardigan or outer shirt off. Here are some more ideas: Wear a lacy shirt over a similar-colored tank top. If you live in a cooler climate, you can try wearing a tank top or shirt-sleeved shirt under a turtleneck. Pair a button-up shirt with a knit shirt. You can wear a tank top, short-sleeved shirt, or long-sleeved shirt depending on how warm or cool it is in your area. The layering will keep you warm in the morning, and you can take the button-up shirt off when it gets warmer. Fall is all about contrast: summer turning into winter, life turning to death, and warm turning to cold. Consider pairing solids with patterns, lights with darks, and mixing textures. Here are some ideas to get you started: Try pairing leather and lace. The two textures work well together because they are so different. Another way to mix and match textures is by wearing knit boot cuffs with some leather boots or solid-colored leggings. Wear a a dark-colored shirt under a light-colored sweater. Mix and match patterns, such as a red plaid button-up shirt with a white undershirt, or a dark-floral skirt with a black, lacy shirt. Pair a flowing, boho blouse with some skinny jeans and boots. Secure the blouse around your waist with a colorful silk scarf or a wide, leather belt.
Summary: Try wearing boots with jeans. Layer skirts and dresses over leggings and tights. Bring out the outerwear. Layer your shirts. Mix and match.

In one sentence, describe what the following article is about: It's easy to see the principles of enthalpy in action with a simple experiment. To make sure that the reaction in your experiment will take place without any foreign contamination, clean and sterilize the container that you plan to use. Scientists use special closed containers called calorimeters to measure enthalpy, but you can achieve reasonable results with any small glass jar or flask. Regardless of the container you use, fill it with clean, room-temperature tap water. You'll also want to conduct the reaction somewhere indoors with a cool temperature. For this experiment, you'll want a fairly small container. We'll be testing the enthalpy-altering effects of Alka-Seltzer on water, so the less water used, the more obvious the temperature change will be. Grab a thermometer and set it in the container so that the temperature-reading end sits below the water level. Take a temperature reading of the water for our purposes, the temperature of the water will represent T1, the initial temperature of the reaction. Let's say that we measure the temperature of the water and find that it's exactly 10 degrees C. In a few steps, we'll use this sample temperature reading to demonstrate the principals of enthalpy. When you're ready to start the experiment, drop a single Alka-Seltzer tablet into the water. You should notice it immediately start to bubble and fizz. As the tablet dissolves in the water, it breaks down into the chemicals bicarbonate (HCO3-) and citric acid (which reacts in the form of hydrogen ions, H+). These chemicals react to form water and carbon dioxide gas in the reaction 3HCO3 + 3H+ 3H2O + 3CO2. Monitor the reaction as it proceeds the Alka-Seltzer tablet should gradually dissolve. As soon as the tablet finishes its reaction (or seems to have slowed to a crawl), measure the temperature again. The water should be slightly colder than before. If it's warmer, the experiment may have been affected by an outside force (like, for instance, if the room you're in is especially warm). For our example experiment, let's say that the temperature of the water is 8 degrees C after the tablet has finished fizzing. In an ideal experiment, when you add the Alka-Seltzer tablet to the water, it forms water and carbon dioxide gas (the latter of which can be observed as fizzing bubbles) and causes the temperature of the water to drop. From this information, we would expect the reaction to be endothermic that is, one that absorbs energy from the surrounding environment. The dissolved liquid reactants need extra energy to make the jump to the gaseous product, so it takes energy in the form of heat from its surroundings (in this case, water). This makes the water's temperature fall. In our example experiment, the temperature of the water fell two degrees after adding the Alka-Seltzer. This is consistent with the sort of mildly endothermic reaction we'd expect.
Summary:
Grab a clean container and fill it with water. Insert a thermometer into the container. Add one Alka-Seltzer tablet to the container. Measure the temperature when the reaction finishes. Estimate the enthalpy of the reaction.
