Physics Quiz: Heat

Specific Heat Capacity: What is the formula to calculate specific heat capacity?

• P = VI

• F = ma

• Q = mcΔT

• E = mc^2

Specific Heat Capacity: What is the specific heat capacity of water?

• 4.18 J/g°C

• 5.20 J/g°C

• 2.50 J/g°C

• 3.75 J/g°C

Specific Heat Capacity: How does the specific heat capacity of a substance affect its ability to store heat?

• It makes the substance less likely to change temperature

• It causes the substance to lose heat more quickly

• It affects the substance's ability to store heat by determining how much heat energy it can absorb or release.

• It has no effect on the substance's ability to store heat

Specific Heat Capacity: Give an example of a substance with a high specific heat capacity and explain its significance.

• Water

• Iron

• Copper

• Aluminum

Specific Heat Capacity: How does the specific heat capacity of a substance affect its temperature change when heated?

• It determines the temperature change when heated.

• It causes the substance to cool down instead of heating up

• It only affects the color of the substance

• It has no effect on the temperature change

Thermal Expansion: What is thermal expansion?

• The tendency of matter to change in shape, area, and volume in response to a change in temperature.

• The tendency of matter to change in state from solid to liquid in response to a change in temperature.

• The tendency of matter to change in color in response to a change in temperature.

• The tendency of matter to change in density in response to a change in temperature.

Thermal Expansion: Give an example of a material that expands when heated and explain its significance.

• Metal

• Wood

• Plastic

• Glass

Thermal Expansion: How does thermal expansion affect the design of bridges and railways?

• Thermal expansion has no impact on the design of bridges and railways

• Thermal expansion makes bridges and railways more durable

• Thermal expansion only affects small structures, not bridges and railways

• Thermal expansion can cause stress and deformation in the structure of bridges and railways, leading to potential damage or failure.

Thermal Expansion: What is the coefficient of linear expansion?

• It is a variable that changes with temperature

• It is a unit of measurement

• It is a material-specific constant.

• It is always 0

Thermal Expansion: How does thermal expansion relate to the concept of temperature?

• Thermal expansion is inversely related to temperature

• Thermal expansion is directly related to the concept of temperature.

• Thermal expansion has no relation to temperature

• Thermal expansion decreases as temperature increases
