Answer:
30284.88J
Explanation:
Given parameters:
Mass of ethanol = 257g
Specific heat capacity of ethanol = 2.4J/g°C
Temperature change = 49.1°C
Unknown:
Amount of heat = ?
Solution:
The quantity of heat need to cause a temperature change on a body is given as;
H = m c Δt
where m is the mass
c is the specific heat capacity
Δt is the change in temperature
All units in proper dimensions. Input the parameters and solve for H;
H = 257 x 2.4 x 49.1
H = 30284.88J
