1.6 - specific heat capacity

Question 1

what is internal energy and what are its two components?

Answer 1

internal energy (thermal energy) is the total energy stored by the particles in a substance or system. It includes the kinetic energy stores and potential energy stores of particles.

Question 2

what is specific heat capacity? (in words)

Answer 2

the amount of energy to raise the temperature of 1kg of a substance by 1 C

Question 3

what is the formula that uses specific heat capacity to find energy change?

Answer 3

(triangle)E = m c (triangle)T

Question 4

will an object with a higher specific heat capacity require more or less energy to raise its temperature?

Answer 4

an object with a higher specific heat capacity will require more energy to raise its temperature.
