# The specific heat capacity of platinum is 0.032 cal/g·K. How to calculate the heat, in joules, necessary to raise the temperature of a sample of platinum weighing 20.0 g from 15.0 Celsius to 65.0 Celsius?

##### 1 Answer

You have to convert either the specific heat of platinum, or the actual heat required from **Cal/g K** to **J/g K**. I"ll convert the specific heat and calculate the heat directly in Joules.

So, in order to get from calories per g Kelvin to Joules per g Kelvin you must use a conversion factor

The relationship between heat and temperature change is expressed mathematically through this equation

Solving for

Notice how little energy is needed to raise the temperature of a
