Suppose you apply a flame and heat one liter of water, raising its temperature 10ºC.
 
How much will the temperature rise if you transfer the same heat energy to 2 liters? 

How much will the temperature rise if you transfer the same heat energy to 3 liters? 

Refer to the following information for the next three questions.

A thermometer is in a container half-filled with 20ºC water.
When an equal volume of 20ºC water is added, the temperature of the mixture is:
 
When instead an equal volume of 40ºC water is added, the temperature of the mixture will be
 
When instead a small amount of 40ºC water is added, the temperature of the mixture will be



 
Refer to the following information for the next four questions.

A red-hot piece of iron is put into a bucket of cool water. Mark the following statements true or false.

You may ignore any heat
transferred to the bucket.
The decrease in iron temperature equals the increase in the water temperature.
 
The quantity of heat lost by the iron equals the quantity of heat galned by the water.
 
The iron and water both will reach the same temperature.
 
The final temperature of the iron and water is halfway between the initial temperatures of each.
