FAQs

Question: What is the difference between heat and temperature?
Answer: Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

Question: How can I calculate the specific heat capacity of a substance?
Answer: Specific heat capacity can be calculated using the formula: \( c = \frac{Q}{m \Delta T} \), where \( Q \) is the heat added, \( m \) is the mass, and \( \Delta T \) is the change in temperature.
