Heat Energy Investigation

Thermal Energy Study In this experiment we measure voltage, current, time, starting temperature, final temperature, and the masses of seven different substances as accurately as possible. In order to make the experiment more accurate, measure the voltage so that the voltage is kept at 12v each time the experiment is done. This is because it may affect the overall result. It also needs to be part of the equations to be completed later.

Heat and temperature • Heat is a kind of energy. • Heat is a measure of total kinetic energy of particles in the body. Heat is measured in Joules (J) or kilojoules (kJ). • Thermal energy flows from a hot object to a cold object. • The amount of heat in a human body depends on its mass, temperature, and the material made from it. • High temperature. • Temperature is a measure of the average kinetic energy of particles in the body. • At absolute zero, the kinetic energy of the particle is zero. • As heat is applied to the body, the temperature rises (unless the condition changes). • The temperature scale used is Celsius (° C) and Kelvin (K).

Please solve the movement. · Compare heat, heat and temperature. • Change the phase change to latent heat and change the potential energy of the particle without changing the average kinetic energy (temperature) of the particle. • Compare conduction, convection, radiation as a means of energy transfer. SC.3.6.2 describes the laws of conservation of energy in mechanical systems from the perspective of kinetic energy, potential energy and heat. Last Updated: September 2014 • Show examples of relationships of kinetic energy, potential energy and heat, indicating that the total energy of mechanical system such as pendulum, roller coaster, car / ball on lamp is saved I will. • A system of related friction type converts mechanical energy into heat.
