Question

A 15.g piece of cadmium metal absorbs 134J of heat while rising from 24.0°C to 62.7°C. Calculate the specific heat of cadmium.

a) 0.45 J/g°C
b) 0.65 J/g°C
c) 0.90 J/g°C
d) 1.20 J/g°C

Answer 1

The specific heat of cadmium is approximately 0.90 J/g°C.

Step-by-step explanation:

The specific heat of a substance is defined as the amount of heat required to raise the temperature of 1 gram of the substance by 1 degree Celsius. To calculate the specific heat of cadmium, we can use the formula:

Specific heat = (Heat absorbed) / (Mass x Change in temperature)

Plugging in the given values, we get:

Specific heat of cadmium = 134 J / (15 g x (62.7°C - 24.0°C))

Simplifying the equation gives us a specific heat of approximately 0.90 J/g°C.
