Use the formula:
Q = q * m;
Formula designation:
q is the specific heat of combustion of alcohol.
m is the mass of alcohol.
The meaning of the quantities:
q = 30 * 10 ^ 6 J / kg;
m = ro * V:
V is the volume of alcohol;
ro is the density of alcohol;
ro = 789 kg / m ^ 3;
Let’s transform the formula:
Q = ro * V * q;
Q = 2367 * V * 10 ^ 6 J.
Answer: Q = 2367 * V * 10 ^ 6 J.
