Calculations with Specific Heat

The change in thermal energy when a substance heats or cools is proportional to the (a)   and the (b)   of the substance. The constant of proportionality is the (c)   (c).

The ​ (a)   of a material is the amount of heat ​ (b)   to raise the temperature of 1 ​ (c)   unit of the material by 1 temperature unit. For example, the specific heat of water is c = 1 cal/g°C. This means it takes 1 calorie of energy to raise the temperature of 1 gram of water by 1°C.

Specific Heat Capacity definition

• Specific heat capacity is the total energy contained in a substance.
• Specific heat capacity is the heat required to raise the temperature of one unit mass of a substance by one degree Celsius.
• Specific heat capacity is the temperature at which a substance changes state.
• Specific heat capacity is the amount of heat lost by a substance when it cools down.

High specific heat requires a large ​ (a)   for a given temperature ​ (b)   .

Low specific heat only requires a small transfer of heat for the same temperature change.

There is low and high specific heat. Low can do the same temp change with only needing a small transfer of heat but high needs larger transfer of heat for that temp change.

• Low specific heat requires less heat transfer for a temperature change compared to high specific heat.

  True

• Low specific heat can only change temperature with a large transfer of heat.

  False

In equation form, the quantity for heat transfer (ΔQ) equals the product of the specific heat (c), the mass (m), and the temperature change (ΔT).

pick 2

• ΔQ = c * m * ΔT
• ΔQ = c / m * ΔT
• ΔQ = c + m + ΔT
• ΔQ = mcΔT

What does the q stand for in Specific Heat Capacity formula?

pick 2

• q stands for the amount of heat energy.
• q stands for the quantity of mass.
• heat energy transferred to or from a substance; it represents the amount of heat gained or lost by a system, typically measured in joules (J).

• q indicates the rate of temperature change.

One more time. What the c stand for and what the q stand for?

pick 4

• amount of heat needed to raise the temperature of one unit mass of a substance by one degree Celsius

  c

• c is the specific heat capacity

• q is the energy transferred to or from a substance

• energy is being transferred to one thing to another

  this is q
