What was the initial temperature is 250 calories reply .1 kg of gold the final temperature of the gold was 175°c ? the specific heat cold is 0.175 °c

Explanation:

When an amount of energy Q is supplied to a substance of mass m, the temperature of the substance increases by , according to the equation

where is the specific heat capacity of the substance.

In this problem, we have:

is the amount of heat supplied to the sample of gold

m = 0.1 kg = 100 g is the mass of the sample

is the specific heat capacity of gold

Solving for , we find the change in temperature

And since the final temperature was

The initial temperature was

frequency or wavelenth of em radiation in a vacuum
