Why do you get heat?
Quite simply, heat occurs because the molecules in an object or substance move very quickly. All matter, or substances, contain molecules which are always in a state of motion, and actions such as movement can make the molecules move faster, creating heat. Heat transfers because it is energy which travels in waves, and when it touches something else, the molecules in the new item or substance also become excited, moving faster and faster to create heat.
Why cooling takes place when sudden expansion of gases occur?
we already know that by expension the kinetic energy of molecules decreases hence causes a little decrease in temperature but when suuden expension takes place then fast moving molecules takes energy from that area and rapidly decrases temperature. Now let's prove it mathematically we know that PV=nRT when expension occurs pressure decreases more than volume increses hence PV product decreases on the right hand R & n are same hence temperature decreases.
Does sound travel travel faster through solid or gas?
Sound travels faster through solids. It does this because sound is generated mainly due to the mediums molecule vibration in a pattern. In solids, the molecules are more closely packed when compared to gases. Hence, the vibration occurs faster and hence the sound is tramsmitted sooner
How do conduction occur?
Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object. As they collide, the faster molecules give up some of their energy to the slower molecules. The slower molecules gain more thermal energy and collide with other molecules in the cooler object. This process continues until heat energy from the warmer object spreads throughout the cooler object.
The transfer of energy that occurs when molecules bump into one another is?
Conduction

Why diffusion become faster on heating explain?
So the molecules move faster and there will be more spontaneous spreading of the material which means that diffusion occurs. So the molecules move faster and there will be more spontaneous spreading of the material which means that diffusion occurs.
When heat is added to water what occurs?
makes the molecules in the water move faster.
What occurs when molecules are heated in a solid or liquid?
In both cases, the molecules start vibrating faster. This is why temperature is also called "molecular kinetic energy" -- it is how fast molecules are vibrating and hitting each other.

What is it called Fewer molecules spread apart?
When a liquid or gas is heated, the molecules move faster, bump into each other, and spread apart. Because the molecules are spread apart, they take up more space. They are less dense. The opposite occurs when a liquid or gas is cooled.
Structural unemployment occurs when?
The need for a particular skill decreases
What condition occurs when the median nerve in the wrist is compressed?
Carpal tunnel syndrome.
What is an economic situiton that occurs when the value of a country's money decreases?
Inflation.
