A technician freezes some ethanol by removing 9.53x10^4 J of heat energy from it at its melting point. What mass of the ethanol is she freezing?
What equation do you think you need to use here? What information do you think you need to have to work out this problem?A technician freezes some ethanol by removing 9.53x10^4 J of heat energy from it at its melting point. What mass of the ethanol is she freezing?
Wouldn't the technician have to lower the temperature to the freezing point? Do you know an equation that related heat energy to temperature?No idea
