What happens to the density of the substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.

What happens to particles during the process of convection?
The particles move around from one place to another through the flow of thermal energy during convection.
What happens to the thermal energy of a substance during a change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
Does water absorb thermal energy during condensation?
No, water releases thermal energy during condensation. It absorbs thermal energy during evaporation, which is why the evaporation of sweat cools your skin.
What happens to density during thermal expansion?
Higher the temperature the lower the density
What happens to a muscle contraction if there is an excess amount of either Ca2 plus or ATP present during the contraction?
During muscle contraction the actin heads pull the sarcomere closed

What happens to the h zone during contraction?
width of H zone decreases
What happens to the strength of contraction during wave summation?
It increases about to about four times greater than a normal contraction for skeletal muscle.
What happens to the volume of a material during thermal contractions?
It becomes smaller.
What happens to the gases given off during a supernova?
they produce thermal energy
What happens during thermal shock?
During thermal shock the temperate rises or falls at an unstable rate. When this occurs it can cause the structural integrity of an object to become damaged.
What happens to z line disc during contraction?
it comes closer and m line becomes dense
