| January 13, 2021 | education
Given:
m = 5 kg;
t1 = 100 ° C;
t2 = 0 ° C;
c = 4200 J / kg * ° С – specific heat capacity of water.
To find:
Q -?
Decision:
In order to find out how much energy water will release, we will use the formula: Q = c * m * (t1 – t2) = 4200 * 5 * (100 – 0) = 2100000 J;
Answer: 2,100,000 Joules of energy will be released.
