теплота пойдет на совершение работы и увеличение внутренней энергии
q = a +δu
a = p * δv = m/µ * r * δt
при изобарном увеличении объема v в 3 раза, температура увеличивается в 3 раза
δt = 3 t₀ - t₀ = 2 t₀
m/µ = 2 по условию (это число молей), тогда a = 4 * r * t₀
для одноатомного газа δu = 3/2 * m/µ * r * δt = 3/2 * 2 * r * 2 * t₀ = 6 * r * t₀
q = a +δu = 4 * r * t₀ + 6 * r * t₀ = 10 * r * t₀
r - универсальная газовая постоянная
Как я провел летние каникулы
Весь список топиков на тему «Мои каникулы / My vacation» смотрите здесь
I think summer is the best season of all because it is warm, the nature is beautiful and we have great opportunities for rest. Summer is a time of holidays. We can go anywhere, spend our time near a river or a lake on fresh, green grass, swim in warm water, or climb mountains, play different games, ride a bicycle and so on.
I spend my summer holidays at my granny’s. There are many things there to do. What I did most of the time - I swam in the sea and sunbathed. Sometimes I made a fire with my friends at the seaside and cooked potatoes there. It was wonderful. We told anecdotes to each other, and did everything we wanted. I also got used to walk alone in the forest.
