Answer:
45.73°C
Explanation:
Given parameters:
Quantity of heat = 2355cal
Mass of water = 51.5g
Unknown:
Change in temperature = ?
Solution:
To solve this problem, use the expression below;
H = m c Ф
H is the quantity of heat
m is the mass
c is the specific heat of water = 1cal/g°C
Ф is the change in temperature = ?
Now insert the parameters and solve;
H = 51.5 x 1 x Ф
2355 = 51.5 x Ф
Ф = 45.73°C
