It amazed me-every time I saw Joe he was smiling. It didn't matter whether he had to 1 at a stop light, or if he were the seventh person in 2 at the bank , and the teller closed her window just 3 he got there. Joe always smiled. It made me wonder why he always seemed so 4 . Having observed Joe with other people, I also noticed something else. Joe 5 people how they were doing, and really seemed to listen to their answers. He was 6 if someone was hurt , and had kind words, and 7 to help in any way he could. It made me think… what if I tried to smile more? An 8 of sorts began when I went to a grocery store. I 9 as I went up and down the aisles (过道)... and people I didn't even 10 smiled back at me. Some even 11 ! The little kid in the cart who was giving his mother a 12 time saw me smile and stopped talking…and, you guessed it-he made a little 13 attempt at a smile. The man in the handicapped cart 14 a person to reach something… I could get that for him. The smile even 15 to him, and he thanked me and smiled at me. As I 16 home, I was smiling. I thought about what I had just 17 , and when someone passed my car and gave me a gesture, I smiled at him. He looked 18 .

小华家的太阳能热水器的水箱内储有50kg水,水的初温为18℃,若淋浴时所需热水的温度为38℃,试计算:
(1)把50kg水从18℃高到38℃吸收的热量是多少J?[c水=4.2×103J/(kg•℃)]
(2)假设煤炭燃烧时产生的热量只有40%被水吸收,若用煤炭加热时需要完全燃烧多少kg的煤炭?(煤炭的热值q=3.0×107J/kg)
