General Chemistry | Heat Capacity (q=smΔT) [Example 2]
Here, we perform a sample calculation for heat capacity in which we solve for a temperature (T) using q=smΔT.
Professor Dave Explains
Practice Problem: Enthalpy of Vaporization
Can we do stoichiometry regarding phase changes? Sure! If we know how many moles of a substance we have, and the energy associated with each mole of that substance undergoing a particular phase change, we can get the energy associated...

If Our Body Temperature is 37° C, Why Do We Feel Hot When it’s 37° C Outside?
Everyone says that the ‘optimum’ body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit). But if the temperature of your surroundings is 37 degrees Celsius, most people will start to feel warm or even hot. Why does that happen?...
