A cube of steel with a mass of 150 grams is heated from 60°C to 150°C. Use calorimetry to determine the amount of energy absorbed by the
metal. The specific heat capacity of steel is 0.466 J/g°C.

1.

The energy lost by the water is given by:

where

m = 3.0 kg = 3000 g is the mass of water

Cs = 4.179 J/g•°C is the specific heat

is the change in temperature

Substituting,

2.

The energy added to the aluminium is given by:

where

m = 0.30 kg = 300 g is the mass of aluminium

Cs = 0.900 J/g•°C is the specific heat

is the change in temperature

Substituting,

4. 42.9 g

The mass of the water sample is given by

where

is the heat added

is the temperature change

Cs = 4.179 J/g•°C is the specific heat

5. 115.5 J

The heat used to heat the copper is given by:

where

m = 5.0 g is the mass of copper

Cs = 0.385 J/g•°C is the specific heat

is the change in temperature

6. 0.185 J/g•°C

The specific heat of iron is given by:

where

Q = -47 J is the heat released by the iron

m = 10.0 g is the mass of iron

is the change in temperature

Substituting,

Substituting,

Substituting,

Explanation:

answer; i do believe the correct answer is (river); /// good luck

i believe it is c.) 1575 j.
