What is the energy transfer between particles as they collide within a substance or between two objects in contact called?
Heat: the transfer of energy from the particles of a warmer object to the particles of a cooler object. (Source: Nelson Science and Technology Grade 7 Textbook, page 186.)
When particles collide energy is transferred from?
By the sun
What transfers heat energy between particles as they collide within a substance or between two objects in contact?
You seem to have answered your own question-it is the collisions that transfer energy
When molecules collide and transfer energy it is called what?
resonance
What wave can transfer energy by vibrating particles of matter?
transfer energy by vibrating particles of matter
In which atmospheric layer do particles move rapidly but do not collide often or transfer thermal energy?
mesosphere, stratosphere

What causes the energy transfer in a cup of hot cocoa when cold milk is added?
The energy transfer is due to collision of the particles and or molecules. Cold milk has particles with less average kinetic energy. Hot cocoa has particles with a higher average kinetic energy. When mixed the particles collide and some transfer of KE takes place until they have a new average KE which is between that of the 2 separate substances. This means that the new temperature will be 'warm' or between the 2 original temperatures.
How can energy transfer in a wave?
All waves can be thought of as mechanical waves, like sound waves. If there's an energy source at a point, the particles at that point will oscillate, meaning that they gain energy. These particles will bounce/collide with other particles in the surroundings, transferring this energy to them. In this way, the energy is carried away from the source and transferred somewhere else.
What happens to the reaction rate when reactant particles are able to collide more often and with more energy?
The reaction rate increases when reactant particles are able to collide more often and with more energy.
Which postulates of the kinetic molecular theory explain the observation that a sample of a gas with particles in rapid random motion does not cool down?
According to the kinetic molecular theory, gases consist of particles in constant random motion. Two postulates can explain why a sample of a gas does not cool down: First, the particles have a range of speeds, so while some may collide and transfer energy, others will collide and gain energy. Second, the average kinetic energy of the gas particles remains constant as long as the temperature is constant. Therefore, while collisions may occur and redistribute the energy, the overall average kinetic energy, and hence temperature, of the gas remains constant.
Transfer of enerby by movemont of particles?
The transfer of energy by movement of particles is called Convection.
