calculate the amount of heat required to raise temperature of 8.50g of water from 24°C to 29°C
To calculate the amount of heat required to raise the temperature of a substance, you need to use the specific heat capacity formula. The specific heat capacity of water is 4.18 J/g°C.
The formula for calculating heat (q) is:
q = m * c * ΔT
Where:
q = heat
m = mass of the substance
c = specific heat capacity
ΔT = change in temperature
Given:
m = 8.50 g
c = 4.18 J/g°C
ΔT = (final temperature - initial temperature)
Calculating ΔT:
ΔT = 29°C - 24°C
ΔT = 5°C
Now, substitute the given values into the formula:
q = 8.50 g * 4.18 J/g°C * 5°C
q = 178.15 J
Therefore, the amount of heat required to raise the temperature of 8.50 g of water from 24°C to 29°C is 178.15 Joules.
Joules=8.5 g*(29-24)deg C*4.184 J/g deg C
= 8.5 * 5 * 4.184 Joules
