Question

758 j of heat are added to 0.750 kg of copper. how much does its temperature change?(unit=degrees c) PLEASE HELPPPPPPP MEEEEEE

Answer 1

Answer:

$2.6^{\circ}C$

Explanation:

When a certain amount of heat energy is supplied to a substance, the temperature of the substance increases according to:

$Q=mC\Delta T$

where

Q is the amount of heat energy supplied

m is the mass of the substance

C is the specific heat capacity of the substance

$\Delta T$ is the change in temperature

In this problem:

Q = 758 J is the heat supplied

m = 0.750 kg is the mass

$C=385kg/JC$ is the specific heat of copper

Solving for $\Delta T$, we find the increase in temperature:

$\Delta T=\frac{Q}{mC}=\frac{758}{(0.750)(385)}=2.6^{\circ}C$
