Ques: Answer the following question given this paragraph: The heating curve shown is for water but other substances have similarly shaped heating curves. Suppose you begin with solid water (ice) at -30C and add heat at a constant rate. The heat you add in the beginning will be absorbed as kinetic energy and the temperature of the solid will increase. When you reach a temperature of 0C (the melting point for water), the heat you add is no longer absorbed as kinetic energy. Instead, the added heat is absorbed as potential energy and the particles separate from each other. During the flat part of the curve labeled "melting", heat is being added constantly but the temperature does not increase. At the left edge of this flat line, the water is solid; by the time enough heat has been added to get to the right edge, the water is liquid, but maintains the same temperature. Once all the water is in the liquid form, the added heat will once again be absorbed as kinetic energy and the temperature will increase again. During the time labeled "water being heated as a liquid", all the added heat is absorbed as kinetic energy. Q: In what form is the heat absorbed when you heat ice and it reaches a temperature of 0 c? Choices: - geothermal energy - mechanical energy - radiation energy - potential energy A:
Ans: potential energy

Answer the following question given this paragraph: PV = nRT This equation is known as the ideal gas law. An ideal gas is defined as a hypothetical gaseous substance whose behavior is independent of attractive and repulsive forces and can be completely described by the ideal gas law. In reality, there is no such thing as an ideal gas, but an ideal gas is a useful conceptual model that allows us to understand how gases respond to changing conditions. As we shall see, under many conditions, most real gases exhibit behavior that closely approximates that of an ideal gas. The ideal gas law can therefore be used to predict the behavior of real gases under most conditions. As you will learn in Section 10.8 "The Behavior of Real Gases", the ideal gas law does not work well at very low temperatures or very high pressures, where deviations from ideal behavior are most commonly observed. Q: The important equation pv = nrt holds true for substances in what state of matter? Choices: - solids - liquids - products - gas A:
(A).
gas
Ques:Answer the following question given this paragraph: Food calories are determined by burning the food and measuring the heat released. Q: What property of food is determined by burning the food and measuring the heat released? Choices: - acidity - nutrients - additives - calories A:

Ans:calories
Answer the following question given this paragraph: Soils with lots of very small spaces are water-holding soils. When clay is present in a soil, the soil holds together more tightly. Clay-rich soil can hold more water. Q: The presence of what makes soil hold together more tightly and enables it to hold more water? Choices: - sand - salt - glass - clay A:
clay
