Understanding Specific Heat Capacity

What factor determines which pizza ingredient reaches 200 degrees Celsius first?

• The taste of the ingredient

• The color of the ingredient

• The specific heat capacity of the ingredient

• The price of the ingredient

Why does oil require less energy to increase its temperature by one degree compared to water?

• Because oil is less dense than water

• Because oil has a lower specific heat capacity than water

• Because oil is a better conductor of heat

• Because oil is more viscous than water

How does the specific heat capacity of a substance affect its temperature change?

• A higher specific heat capacity means faster temperature change

• A lower specific heat capacity means no change in temperature

• A higher specific heat capacity means slower temperature change

• Specific heat capacity has no effect on temperature change

Why is water used as a coolant in engines?

• Because it is inexpensive

• Because it is non-toxic

• Because it has a high specific heat capacity

• Because it is readily available

What role does specific heat capacity play in the use of water as a coolant?

• It allows water to absorb a small amount of heat

• It has no role in the cooling process

• It makes water an inefficient coolant

• It allows water to absorb a large amount of heat
