3 cards from this section. Quick, good the night before a test.
Define heat and give its SI unit.
What transfers because of temperature differences?
What is temperature?
What tells us the feeling of hotness or coldness?
What is the SI unit of heat?
Think of what heat transfers in.
True or False: Temperature is dependent on mass.
What remains even if you have more of the same substance?
A liquid with a specific heat capacity of 4.18 J/g·°C is required to increase its temperature from 20 °C to 80 °C with an intake of 1,500 J. What is the mass of the liquid?
Rearrange the formula to solve for mass.
If 250g of ice at -10°C absorbs 25,000 J of heat before melting, calculate how much more heat it requires to raise the temperature of the resulting water from 0°C to 100°C. (c for water= 4.18 J/g·°C)
Consider both melting and heating separately.
