2 cards from this section. Quick, good the night before a test.
Define heat and temperature.
Think about how you measure the warmth of water.
Give an example of thermal equilibrium.
Consider your body and the surrounding air.
What is the role of temperature in heat transfer?
Think about how heat behaves when you touch a hot object.
True or False: Heat can flow from a colder object to a hotter object.
Remember how you experience heat.
A 10 kg block of material at 100°C is placed in 5 kg of water at 20°C. Determine the final equilibrium temperature if no heat is lost to the surroundings (specific heat of water = 4.18 kJ/kg°C).
Use the specific heat formula Q = mcΔT.
Consider a metal rod with a coefficient of linear expansion of 1.5 x 10^-5 K^-1. Calculate how much it expands when heated from 20°C to 100°C, given its original length of 2 meters.
Keep in mind the initial length of the rod.
