Heat (6.1.5)

Question 1

• Heat is a form by which energy is transferred, and is measured by change in
temperature.

Answer 1

• Heat is a form by which energy is transferred, and is measured by change in
temperature.

Question 2

• Heat capacity (C) measures the amount of energy needed to raise the
temperature of a material.

Answer 2

• Heat capacity (C) measures the amount of energy needed to raise the
temperature of a material.

Question 3

• With a constant volume the change in internal energy (∆E) can be calculated by
knowing the heat evolved or absorbed by the system, since the amount of work
done is zero.

Answer 3

• With a constant volume the change in internal energy (∆E) can be calculated by
knowing the heat evolved or absorbed by the system, since the amount of work
done is zero.

Question 4

Heat (q) is a form by which energy is transferred. In
an endothermic process, heat moves into the
system from the surroundings (q > 0). In an
exothermic process, heat moves into the
surroundings from the system (q

Answer 4

Heat (q) is a form by which energy is transferred. In
an endothermic process, heat moves into the
