т.к. масса(объём и плотность) и удельная теплоёмкость одинакова => T1 + T2 = t1 + t2, где T1 = 0 C, t1 = 20 C, t2 = 40 C

T2 = t1 + t2 - T1 = 60 C

I realise now that i was looking for reassurance
Nowadays i never spend more than $10 a week on texts,is the goal I set with my counsellor when I started treatment. When things were really out of control I was sending around 700 texts a week, and in one year I squandered $4,500 on text messaging. That was during a period of real insecurity in my relationship with my girlfriend,and it was kind of comforting to get texts from her: I realise now that I was looking for reassurance,constantly needing to know where she was and what she was up to. It's certainly been much easier since she and I went our separate ways.Apparently, it isn't unusual for people with an addiction to have underlying problems at work or with a relationship.
I was referred to a counselling service after my boss discovered my problem: I had accidentally sent a text which was intended for my girlfriend to one of my colleagues,and then hit the 'resend' button eight times when I didn't get a reply! My boss started keeping an eye on me and took note whenever I reached for my mobile to send or read a message; then he demanded an explanation for all the time I was spending not doing my job . I decided to resign rather than face disciplinary procedures.
My counselor says I'm the first case of text message addiction he's treated in ten years of working in the field , but he also thinks there are a good few people out there who don't realise they have a problem. That may well be true, it's certainly easy to get hooked on texting : no sooner have you sent one message than another comes straight back,kind of like a game of ping-pong

Подчеркни во втором предложении два слова с безударной гласной в корне. подбери проверочные слова. выпиши из последнего приложения слово, в котором букв больше, чем звуков. укажи на колличество слогов в слове. раздели слово черточками для переноса, если это возможно. Приятно в дождливый день сидеть дома и пить чай. под ногами лежит мягкий ковёр. теплые домашние тапочки греют ноги. родители сидят рядом. Мама заварила чай. на столе блюдо с вкусными пирожками. я ем их один за другим. я очень голодный.
