Calculate the amount of energy that is absorbed by 75 g ... water

from 22.5 °C to 37.8 °C. The specific heat of water is 1 cal / g x °C

Q = 1147.5 cal

Explanation:

Given dа ta:

Energy absorbed = ?

Mass of water = 75 g

Initial temperature = 22.5°C

Final temperature = 37.8°C

Specific heat of water = 1 cal/g.°C

Solution:

Formula:

Q = m. c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT = 37.8°C - 22.5°C

ΔT = 15.3 °C

Q = m. c. ΔT

Q = 75 g. 1 cal/g.°C. 15.3 °C

Q = 1147.5 cal
