The original temperature of the copper is 145.4 °C

<h3>What is temperature?</h3>

Temperature refers to the degree of hotness or coldness of a body. Now we know that the heat lost by the copper is equal to the heat gained by the water. The heat lost is negative while the heat gained is positive.

Hence;

-(mcdT)= mcdT

-(80.0 * 0.20 ( 26.9 - T)) = 100 * 4.12 * (26.9 - 22.3 )

-(430.4 - 16T) = 100 * 4.12 * (26.9 - 22.3 )

-430.4 + 16T = 1895.2

T =  1895.2 + 430.4 /16

T = 145.4 °C

The temperature of the copper is 145.4 °C.

Adding energy has no effect on the rate of evaporation? True or False ?
zlopas [31]

Answer:

False

Explanation:

Evaporation occurs when molecules in a liquid gain enough energy that they overcome attractions from other molecules and break away to become a gas. Adding energy increases the rate of evaporation.
