Heat
gained or absorbed in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. The heat capacity of aluminum at 25 degrees celsius is 0.9 J/g-C. It is
expressed as follows:
Heat = mC(T2-T1)
5800 J = 152000(0.90)(ΔT)
ΔT = 0.42 °C change in temperature
Answer: 2.98 K
Explanation:
[tex]Q= m\times c\times \Delta T[/tex]
Q= heat gained or released= 5800 J
m= mass of the substance = 15.2 kg = 15200 g (1kg=1000g)
c = heat capacity of lead= 0.128 J/gK
[tex]\Delta T={\text{Change in temperature}}=?[/tex]
[tex]5800J=15200g\times 0.128J/gK\times \Delta T[/tex]
[tex]\Delta T= 2.98K[/tex]
Thus change in temperature is 2.98 K.
