100 g of sunflower oil is poured into the calorimeter at a temperature of 20 ° C. Then a copper piece with a mass of 50 g, heated to 200 ° C, is thrown into the oil. What is the oil temperature set in the calorimeter?
Solution:
1700 * 0.1 * (Ttr – 20) = 400 * 0.05 * (200 – Ttr)
170tr – 3400 = 4000 – 20tr
190Ttr = 7400
Ttr = 39 ° C
Answer: Ttr = 39 ° С
