Question 1.
What is the unit of heat?
Show hintHide hint
Think about energy units.
Question 2.
Is temperature the same as thermal energy?
Show hintHide hint
Recall the definitions of both terms.
3Question 3.
What is the specific heat capacity of a substance?
- The heat required to change its state
- The heat required to raise its temperature by 1°C
- The total internal energy of the substance
Show hintHide hint
Focus on how specific heat is defined.
4Question 4.
What type of heat transfer occurs without direct contact?
- Conduction
- Convection
- Radiation
Show hintHide hint
Consider heat transfer methods that use waves.
Question 5.
Calculate the heat required to melt 5 kg of ice at 0°C to water at 0°C, given the latent heat of fusion of ice is 334,000 J/kg.
Show hintHide hint
Remember the melting process uses latent heat of fusion.
Question 6.
A gas with a volume of 0.1 m³ and pressure 200,000 Pa is heated, and its volume changes to 0.2 m³. Calculate the new pressure using the Ideal Gas Law if temperature remains constant.
Show hintHide hint
Isolate the pressure using the relationship of initial and final states.
