Worksheet: Specific Heat
In this worksheet, we will practice calculating the specific heat of a material from a change in temperature and the amount of heat transferred.
Object A, at , and object B, at , are brought into contact with one another. In which direction does thermal energy flow?
- AFrom object A to object B
- BFrom object B to object A
- CIn neither direction
A chemical reaction heats a 10 cm3 block of tin (density 7.31 g/cm3) by . The same reaction heats a 15 cm3 block of lead (density 11.3 g/cm3) by .
What is the specific heat of tin, , as a multiple of the specific heat of lead, ?
An insulated cup contains 100 mL of water at . When this water is warmed, its density and specific heat remain approximately constant. Which of the following, if poured into the cup, would increase the temperature of its contents by the largest amount?
- A80 mL of water at
- B40 mL of water at
- C5 mL of water at
- D10 mL of water at
- E20 mL of water at
A 70.0 g piece of metal at is placed into 100 g of water at . The metal and water reach a constant temperature of , and no heat is lost to the surroundings. The specific heat of water is .
To 3 significant figures, how much heat is transferred from the metal to the water?
What is the specific heat of the metal?
