Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of the following best defines specific heat capacity?
The amount of heat required to change the state of a substance.
The amount of heat required to raise the temperature of 1 kg of a substance by 1 Kelvin.
The total heat content of a system.
The rate at which heat is transferred.
2. Water has a high specific heat capacity. This means that:
Water heats up quickly and cools down quickly.
Water requires a large amount of heat to change its temperature.
Water is a good conductor of heat.
Water has a low boiling point.
3. The formula used to calculate the amount of heat energy (Q) absorbed or released is Q = m × c × ΔT, where 'm' stands for , 'c' stands for , and 'ΔT' stands for .
4. Units for specific heat capacity are typically .
5. Explain why coastal regions tend to have milder climates than inland regions.
6. A 0.5 kg block of aluminum (specific heat capacity = 900 J/kg°C) absorbs 18,000 J of heat. If its initial temperature was 20°C, what is its final temperature?
