Calculate the amount of heat required to raise the temperature of a 39g sample of water from 6∘C to 23∘C.
q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
To calculate the amount of heat required to raise the temperature of a substance, you need to use the formula:
q = m * c * ΔT
where:
q is the heat transferred
m is the mass of the substance
c is the specific heat capacity of the substance
ΔT is the change in temperature
In this case, the substance is water, which has a specific heat capacity of 4.18 J/g°C.
Step 1: Determine the mass of the water sample.
Given: mass = 39g
Step 2: Calculate the change in temperature (ΔT).
Given: initial temperature = 6°C
final temperature = 23°C
ΔT = final temperature - initial temperature = 23 - 6 = 17°C
Step 3: Plug the values into the formula and solve for q.
q = m * c * ΔT
q = 39g * 4.18 J/g°C * 17°C
q = 2691.06 J
Therefore, the amount of heat required to raise the temperature of the 39g sample of water from 6°C to 23°C is approximately 2691.06 J.
