Answer the following question given this paragraph: To sterilize a 50.0-g glass baby bottle, we must raise its temperature from 22.0C to 95.0C . How much heat transfer is required? 4. The same heat transfer into identical masses of different substances produces different temperature changes. Calculate the final temperature when 1.00 kcal of heat transfers into 1.00 kg of the following, originally at 20.0C : (a) water; (b) concrete; (c) steel; and (d) mercury. Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 20 rubs, at a distance of 7.50 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed is only 0.100 kg, mostly in the palms and fingers. A 0.250-kg block of a pure material is heated from. Q: Rubbing your hands together warms them by converting work into what energy? Choices: - kinetic energy - motion energy - layer energy - thermal energy A:
thermal energy

Answer the following question given this paragraph: Introduction Plants are as essential to human existence as land, water, and air. Without plants, our day-to-day lives would be impossible because without oxygen from photosynthesis, aerobic life cannot be sustained. From providing food and shelter to serving as a source of medicines, oils, perfumes, and industrial products, plants provide humans with numerous valuable resources. When you think of plants, most of the organisms that come to mind are vascular plants. These plants have tissues that conduct food and water, and they have seeds. Seed plants are divided into gymnosperms and angiosperms. Gymnosperms include the needle-leaved conifersspruce, fir, and pineas well as less familiar plants, such as ginkgos and cycads. Their seeds are not enclosed by a fleshy fruit. Angiosperms, also called flowering plants, constitute the majority of seed plants. They include broadleaved trees (such as maple, oak, and elm), vegetables (such as potatoes, lettuce, and carrots), grasses, and plants known for the beauty of their flowers (roses, irises, and daffodils, for example). While individual plant species are unique, all share a common structure: a plant body consisting of stems, roots, and leaves. They all transport water, minerals, and sugars produced through photosynthesis through the plant body in a similar manner. All plant species also respond to environmental factors, such as light, gravity, competition, temperature, and predation. Q: Angiosperms are also known as what? Choices: - dry plants - uncommon plants - dead plants - flowering plants A:
**Answer**
flowering plants
(Question)
Answer the following question given this paragraph: In everyday speech, the terms accuracy and precision are frequently used interchangeably. However, their scientific meanings are quite different. Accuracy is a measure of how close a measurement is to the correct or accepted value of the quantity being measured. Precision is a measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value. Q: In contrast to precision, this term means how close a measurement is to the correct or accepted value of the quantity being measured? Choices: - diversity - frequency - deviant - accuracy A:
(Answer)
accuracy
