Card preview (10)
______ energy is transferred through the hydrosphere from warmer latitudes to colder polar regions largely due to global ______
Thermal Winds
The ______ ______ ______ is the amount of heat energy needed to raise the temperature of 1g of a substance by 1°C
Specific heat capacity
______ of ______ energy is the amount of ______ energy that is released or absorbed by 1g of a substance as its temperature changes by 1°C
Quantity Thermal Thermal
The ______ cycle: During a phase change, the temperature of water remains ______
Hydrologic Constant
The ______ of ______ of a substance is the amount of energy released or absorbed when it changes from a liquid to solid, or from a solid to a liquid.
Heat of fusion
Q = mc🔺t What are the variables?
Q = thermal energy (J) m = mass (g) c = specific heat capacity (J/g°C) 🔺t = change in temperature (°C)
H(fus) = Q/n What are the variables?
H(fus) = heat of fusion (KJ/mol) Q = thermal energy (KJ) n = # of moles of substance (mol)
n = m/M What are the variables?
n = # of moles of substance (mol) m = mass (g) M = molar mass (g/mol)
The ______ of ______ of a substance is the amount of energy released or absorbed when it changes from a gas to a liquid, or from a liquid to a gas.
Heat of vaporization
H(vap) = Q/n What are the variables?
H(vap) = heat of vaporization (KJ/mol) Q = thermal energy (KJ) n = # of moles of substance (mol)
