Ответ:

47, 52 МДж

Объяснение:

Q = cm(t-to) (to - t начальная)

t-to = 20-50 = -30. Разница в температуре 30 градусов. Теперь подставляем значения в формулу.

Q = 880 * 1800 * 30 = 47520000 Дж = 47520 кДж = 47, 52 МДж

The University consists of 32 colleges: 27 colleges for men and 5 colleges for women. There are 16 faculties there. Oxford (like Cambridge) is a collection of colleges, each self-governing and independent. The colleges are the real living Oxford and each has its own character and individuality. Every college has its arts men and its science men, its medical students and its engineers. Every student follows his own course of study, but he gains a lot from living among those who represent all other branches.
The term of studies lasts for 10 weeks. There are three terms in the Oxford academic year.
Within the first week the freshman meets his tutor who tells the student about his plans, the lectures which he must take, about the requirements for the examination which he will take, about the course of reading for him. Attendance at lectures in not compulsory. Once every week each undergraduate goes to his tutor’s room to read out an essay which he has
written and discuss this essay with the tutor. At the end of each term the progress of the students is tested by the college examinations. They pay great attention to athletics at the University.
The students are engaged in different kinds of sports, take part in competitions between Oxford and Cambridge Universities. This is how a student spends his day. His working hours are from 9 to 1. At 9 o’clock he sees his tutor or goes to the library, or attends lectures. From 2 to 5 he is engaged in sports and all kinds of exercise. From 5 to 7 he works in the library or laboratory. At 7 o’clock they have dinnertime. After dinner the students have club activities, debating societies. By 10 o’clock the student must be in the college, as most of students live in the colleges, only some of them live in lodgings in the town.
