Question

a 4.50 g coin of copper absorbed 54 calories of heat. what was the final temperature of the copper if the initial temperature was 25°C? the specific heat capacity of copper is 0.092 cal/g°C

Answer 1

The final temperature of copper is 155.43°C.

Step-by-step explanation:

The formula to apply is Q=m*Δt*c where ;

Q=heat energy, m=mass, c=specific heat capacity and Δt= change in temperature

Given that Q=54 calories , m=4.50 g and c=0.092 cal/g°C

In this question find Δt then ,the final temperature.

Δt=Q/m*c

Δt=54/4.50*0.092 =130.43°C

To find final temperature, apply the formula;

Δt=Final temperature - Initial temperature

130.43°C=Final temperature-25°C

130.43°C+25°C=Final temperature

155.43°C

Answer 2

The final temperature of copper is 155.43°C.

We use the formula for the heat energy

What is the formula for heat energy?

The formula to apply is  $Q=m*\Delta t*c$

Where;Q=heat energy, m=mass, c=specific heat capacity and Δt= change in temperature

Given that Q=54 calories , m=4.50 g and c=0.092 cal/g°C

first we have to find the Δt

$\Delta t=Q/(m\times c)$

$\Delta t=54/4.50*0.092 =130.43^{0}C$

Next we have to find the final temperature so

What is the formula for final temperature?

$\Delta t=Final temperature - Initial temperature$

plug the value of delta t and initial temperature in above formula we get,

$130.43=Final temperature-25$

$130.43+25=Final temperature$

$155.43=final temperature$

Therefore ,The final temperature of copper is 155.43°C
