The temperature 13
The temperature in Toronto at noon during a winter day measured 4 °C. The temperature started dropping 2° every hour. Which inequality can be used to find the number of hours, x, after which the temperature will measure below -3 °C?
The temperature 12
The temperature of a liquid was 25 °C before being warmed at a rate of 10 °C per minute for 5 minutes. It was then cooled at 3.5 °C per minute for 6 minutes. What was the temperature of the liquid after cooling?
Lower temperature
The temperature level of the liquid in a thermometer is 24.32 °C lower than the boiling point of water. What is the thermometer reading? Show your answer by drawing and shading the thermometer.
Lead melt
Find the heat needed to melt an object made of lead weighing 250 g and an initial temperature of 35 °C. Lead melts at 327 °C at normal pressure. Mass heat capacity of lead c = 129 J/kg • K and mass latent heat of lead lt (t is the subscript) = 22.6 kJ/kg.
