What happens to density of a 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 energy is converted to thermal energy as your muscles contract?
Chemical energy stored in the muscles is converted to thermal energy during muscle contraction. This process is not 100% efficient, with some energy being lost as heat.
What is the force that causes exfoliation?
Exfoliation is primarily caused by a combination of thermal expansion and contraction due to daily temperature fluctuations. The heating of rock during the day causes expansion, while cooling at night causes contraction. This continuous expansion and contraction weaken the rock, leading to exfoliation.
Does the Z line shorten during muscle contraction?
Yes, the Z line shortens during muscle contraction.
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 density during evaporation of salt water?
The density increase.

What happens to the h zone during contraction?
width of H zone decreases
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
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 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 during an eccentric contraction?
During an eccentric contraction, a muscle lengthens while generating tension, typically occurring when it resists a force greater than its own contraction strength. For example, this happens when lowering a weight or during the downward phase of a squat. Eccentric contractions play a crucial role in controlling movement and absorbing shock, helping to prevent injuries. This type of contraction is characterized by a gradual increase in muscle tension while the muscle is elongating.
