A student mixes 100 g of water at 80 °C with 100 g at 20 °C in an insulated container. What is the final temperature (neglect heat loss)?
Which change would increase the rate at which a hot metal block cools in air?
Why is thermal energy stored during melting not associated with a temperature change?
Two identical blocks at the same initial temperature are left to cool: block A is matt black and block B is shiny silver. Which statement is correct about thermal radiation?
A 2.0 kg block of iron (c = 450 J/kg °C) is heated from 20 °C to 80 °C. How much energy is stored as thermal energy?
Which factor affects the thermal energy stored in a substance at a given temperature?
A block of metal has mass 2.0 kg and is heated so its temperature rises from 20 °C to 50 °C. If 25 200 J of energy is supplied, what is the specific heat capacity of the metal?
Which of the following best describes specific latent heat of fusion?
Why do polished shiny surfaces radiate less thermal infrared than rough dark surfaces?
During a cooling experiment the time for a fixed ?T increases when using thicker insulation. Which conclusion is best?
What does a negative temperature change (?T) indicate in the equation Q = m c ?T?
