Answer:
Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator, increasing the volume decreases the density.
Explanation:
When the thermal energy of the air around a fire is transferred to the surrounding air A. The thermal energy is spread out by the surrounding air.
Thermal energy transfers occur in 3 approaches conduction, convection, and radiation. whilst thermal power is transferred among neighboring molecules that are in touch with each other, which is referred to as conduction.
Thermal strength refers to the power contained inside a system that is liable for its temperature. heat is the go with the flow of thermal electricity. an entire department of physics, thermodynamics, offers how heat is transferred among exceptional systems and how work is accomplished in the manner.
Thermal strength also referred to as heat strength is produced when a rise in temperature reasons atoms and molecules to transport quicker and collide with each other. The energy that comes from the temperature of the heated substance is referred to as thermal strength.

I believe that the subject is supposed to be science
Answer:
7.2 meters per hour
Explanation:
It is given that,
The speed of a paramecium is 2,000 micrometers per second.
We need to find the speed of the paramecium in meters per hour.
We know that,
and
1 hour = 3600 seconds
Hence, the speed of the paramecium is 7.2 meters per hour.
About 450*C, a pressure of about 200atm and a catalyst or iron
