(b) (i)The tile floor feels colder than the wooden floor even though both floor materials are at the
same temperature. Give explanation.
(ii) A faulty thermometer has its fixed points marked 0°C and 95°C. What is the correct
temperature in centigrade when this thermometer reads 59°C?
(c)A liquid cools from 70°C to 50°C in four minutes. If the surrounding temperature is 20°C, how
much time will it take to cool from 50°C to 40°C?
