The heat required to raise the temperature of the cup from 25 c to 50 c is calculated as follows
Q (heat) = c x delta T
c = specific heat capacity = 0. 820 j/c
delta T = change in temperature ( 50 c- 25 c = 25c
= 0.820 j /c x 25 c = 20.5 j
Q (heat) = c x delta T
c = specific heat capacity = 0. 820 j/c
delta T = change in temperature ( 50 c- 25 c = 25c
= 0.820 j /c x 25 c = 20.5 j
Explanation:
Heat is equal to heat capacity multiplied by change in temperature.
Mathematically, [tex]Q = C \times \Delta T[/tex]
where C = heat capacity
[tex]\Delta T[/tex] = change in temperature
Therefore, calculate heat as follows.
[tex]Q = C \times \Delta T[/tex]
= [tex]0.820 j^{o}C \times (50.0 - 25.0)^{o}C[/tex]
= 20.5 j
Thus, we can conclude that heat is required to raise the temperature of the cup is 20. 5 joules.
