The meaning of heat
what is the energy of moving particles
temperature meaning
what is the measure of the average kinetic energy in a substance (or the measure of how 'hot' or 'cold' a substance is)?
3 good conductors
what is copper, gold, graphite, any other metal, water, aluminum, and more?
three states of matter
what is gas, liquid, and solid?
conduction
what is the transfer of heat through contact
thermal energy
what is the total kinetic energy of all the particles a substance contains?
plastic is an insulator
what is true?
cold makes things ___ and heat makes things ___
what is contract, expand
geothermal energy?
what is the heat and energy generated from the magma deep inside our planet?
heat energy
what is the transfer of heat from one object to another
difference between heat and temperature?
Ceramic is a conductor
what is false?
movement of the particles in a solid
what is vibrating or moving quickly in place
cogerneration
what is the process of making electry and useful heat at the same time?
radiation
the transfer of heat through invisible waves (If you said infared waves, even better)
thermal energy cooling?
what is Refrigerant is something that is used to create cool temperatures. It evaporates at a very low temperature which creates freezing temperatures. The refrigerant cools as it evaporated so heat transfers from the warmer air inside the refrigerator to it, so it cools down while the refrigerant heats up, but it is then cooled down again so it can be reused?
oil is a conductor
what is false?
rules of particle model of matter
what is Number 1, all matter is made of tiny particles. Number 2, The particles of matter are always moving. Number 3, The particles have space in between them. Number 4, Adding heat to the particles makes them increase in speed?
3 cons of nuclear energy
what is non-renewable, dangerous, and expensive to build factories for it, requires being smart?
convection
what is heat transfer by particles in a liquid or gas moving in a circular pattern?
thermostat system
what is The switch in a thermostat is a bimetallic strip, which consists of two different metals joined together. When heated, one of the metals expands faster than the other. This causes the strip to bend.The bending effect of the bimetallic strip is used to measure temperature change. As the strip bends and unbends, it opens and closes an electric circuit that controls a heat-regulating device, such as an electric blanket?
7 good insulators
what is plastic, glass, ceramic, rubber, wood, fabric, paper, wool, corks, styrofoam, and more?
thermos uses a ___ to stop radiation
what is a vacuum?
the pros and cons of renewable energy (2 each)
what is
Pros: renewable, less emissions (other)
cons: time, high total cost, can damage ecosystems (hydroelectricity), isn't reliable (other)
