Question

A metal is thought to be gold or titanium. When 20 g of the metal absorbs 30.8 cal, its temperature rises by 50 °C.

a. What is the specific heat, in cal/ g °C, of the metal?

b. Would you identify the metal as gold or titanium?

Step 1

The specific heat capacity of a substance refers to the heat capacity of a substance refers to the heat capacity of the sample divided by the mass of the given sample.

Step 2

The rise in the temperature of the metal is given to be 50oC when it absorbs about 30.8 cal of heat and weighs 20 g.

The specific heat of the metal can be calculated as follows:

heat
Specific heat=
massxAT
30.8 cal
cal
