The specific heat(c) of copper is 0.39 J/g °C. What is the temperature
change(At) when 100 Joules of heat(Q) is added to 20 grams?

The temperature change (∆T) of the copper when 100 Joules of heat is added to 20 grams is 12.82°C

HOW TO CALCULATE TEMPERATURE CHANGE:

Where;

100 = 20 × 0.39 × ∆T

100 = 7.8∆T

∆T = 100 ÷ 7.8

∆T = 12.82°C

12.8°c

Explanation:

specific heat capacity of copper(c)=0.39J*g°c

Mass(m)=20grams

Quantity of heat(Q)=100joules

Temperature rise(@)=?

@=Q/(mxc)

@=100/(20x0.39)

@=100/7.8

@=12.8°c

the closer the planet is to the sun, the larger the gravity

the right answer is 0.3 meters per second
