Find the amount of heat when the water temperature changes from 30 ° to 100 ° C, if the mass of water is 600g.
| March 10, 2021 | education
Given:
t1 = 30 ° C;
t2 = 100 ° C;
m = 600 g = 0.6 kg;
c = 4200 J / (kg * ° C) – specific heat capacity of water;
Find: Q -?
Decision:
Let’s use the formula to find the amount of heat when heated:
Q = c * m * (t2 – t1) = 4200 * 0.6 * (100 – 30) = 176400 J;
Answer: 176400 J.
