Heating Curve of Water
In the Heating Curve above, describe what is happening at areas where the graph has constant temperature.
When melting takes place, what happens to the temperature?
it goes up
is stays the same
it goes down
If q (the amount of heat) is 350 J and you have 3.5 g (the mass), what is the specific heat (C) if the temperature changes 10.0 ºC ? The equation is C = q / m T (T is the change in temp).
When 435 J of heat is added to 3.4 g of olive oil at 21°C, the temperature increases to 85 °C. What is the specific heat of olive oil?
Temperature is the _____________ kinetic energy of the particles in a substance. Heat is the __________________ kinetic energy.
