Heat and Temperature

How is temperature related to heat?

• Temperature is a measure of the heat of an object.

• Heat causes a change in the temperature of an object.

• Raising the temperature causes the heat of an object to increase.

• Temperature and heat are two different ways to measure the same thing.

Gregory is making a turkey for Thanksgiving by roasting it in his oven. The turkey started at a room temperature of 25°C, and the oven was preheated to 175°C. If Gregory accidentally turns off the oven after he places the turkey inside of it, then what will happen to the turkey?

• Thermal energy flows from the oven into the turkey and continues to flow until they reach equilibrium at 100°C or the turkey is removed.

• Thermal energy flows from the turkey into the oven and continues to flow until they reach equilibrium at 100°C or the oven is turned off.

• Thermal energy flows from the oven into the turkey and continues to flow until the turkey reaches its perfect temperature of 74°C.

• Thermal energy flows from the turkey into the oven and continues to flow until the oven is room temperature of 25°C.
