Determine what mass of water taken at 0С can be heated by the heat supplied to the body in the amount of 10 kJ, if the final t 50С
Given:
T1 = 0 degrees Celsius;
T2 = 50 degrees Celsius;
c = 4200 J / (kg * C);
Q = 10,000 Joules.
It is required to determine the mass of water m.
m = Q / (c * dT) = Q / (c * (T2 – T1)) = 10000 / (4200 * (50 -0)) =
= 10000 / (4200 * 50) = 10000 / 210,000 = 0.05 kilograms = 50 grams.
Answer: the mass of water is 50 grams.
