Which of the following statements are true about heating curves. What happens to the particles of a substance as it is heated. 1 Adenine 2 Cytosine 3 Guanine 4 Thymine 5 Uracil.

It shows how the temperature of a substance changes when heated. The temperature was recorded as a 500 g sample of solid ethanol was heated at a constant rate. They release energy into the surroundings.

There are two main observations on the measured curve. Which of the following is true for a heating curve. The change of state behavior of all substances can be represented with a heating curve of this type.

Which of the following statements are true about heating curves. What happens to the heat applied as the temperature is increased. A heating cooling curve shows the changes that occurs when ____ is added to or removed from a sample of matter at a _____ rate Heat constant Within a phase a change in heat causes the temperature of the substance to _____ as the _____ energy of the molecules changes.

Ice is melting to form liquid water. Choose as many as apply. Liquid water is becoming warmer.

Which of these conditions is always true for an exothermic process. Which of the following explains why the slope of segment T is greater than the slope of segment R. The heat capacity of the gas is greater than the heat of fusion.

A constant rate of heating is assumed so that one can also think of the x-axis as the amount of time that goes by as a substance is heated. Temperature is plotted on the y-axis while the x-axis represents the heat that has been added. What happens to the particles of a substance as it is heated.

A heating curve illustrates what a substance looks like as it is heated. The following graph is a heating curve showing the addition heat at a constant rate of 5000 joulesminute to a 300 gram sample of ice of at 200C. The substance must be a salt that dissociates on heating.

On the basis of this heating curve which of the following statement is correct about the substance. Other substances would of course have melting and boiling points that are different from those of water. A heating-cooling curve is constructed by adding or removing heat at a constant rate.
