After
Before
Energy transfer by touch, from particle to particle is called ______________.
Radiation
Convection
Conduction
When the temperature is constant, the system is in a condition called __________________.

The formula to figure out the final temperature is.........
Tf = T1 + T2 / 2
ΔT= Tf - Ti
Cal = m x ΔT
A student places a warm can of fruit juice in a bucket of ice water. What happens to the particles of juice?
The number of juice particles decreases as energy transfers to the ice water.
Energy flow decreases the size of the juice particles.
Cold energy decreases the motion of the juice particles.
Energy flow decreases the speed of the juice particles.
Particles in a solid table and in the air of a classroom are at the same temperature.
Select the true statements below.
The particles in the table and the air have the same average kinetic energy.
The particles in the table are not moving, and the air particles are moving.
The air particles interact with each other differently than how the table particles interact with each other.
Particles interacting as a gas always have more average kinetic energy than particles interacting as a solid.
