What happens when the density of a fluid gets hotter?
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
What happens when two things of different temperatures meet?
When two things of different temperatures meet, heat transfer occurs. The hotter object will transfer heat to the cooler object until they reach thermal equilibrium, where both objects reach the same temperature. This process is known as thermal diffusion.
What happens to the hotter and cooler material in a current?
In a current, the hotter material tends to rise while the cooler material sinks. This is due to the difference in density caused by the variation in temperature. This movement of materials helps transfer heat and redistribute energy in the system.
What is heat and why do some thing things feel hotter than others?
Heat is the average kinetic energy (or energy of movement) of the atomic or molecular constituents of the substance in question. On the sub-microscopic scale, everything vibrates, and the faster the vibration, the higher the temperature. If you have two objects of the same temperature but one feels hotter than the other, it is because the one that feels hotter is a better conductor of heat. If the heat flows faster, the object will feel hotter.
What happens when a hot object comes in contact with a cooler object?
Heat transfer occurs from the hotter object to the cooler object until thermal equilibrium is reached. The hotter object will cool down while the cooler object will heat up until both objects reach the same temperature.
What happens when you go further into the earths crust?
you get hotter and hotter
How do things get hotter and colder?
Things get hotter because of the sun, and things get colder because of the snow
What happens to the brightness of main sequence stars as they get hotter?
As they get hotter, they usually get brighter.
What happens when air gains heat?
It gets hotter
What happens to the density of a fluid when it becomes hotter?
the fluid rises
What happens to a cloud when it becomes denser and hotter?
It usually dissipates.
What happens when density of a fluid when it becomes hotter?
the fluid rises
Will heat gain make things hotter?
yes
What happens when water vapor it gain energy?
It becomes hotter vapour.
What happens to the temperature as you travel closer to the center of the earth?
It gets hotter
What happens when the temperature goes up and the fans don't work?
you get hotter
What happens when the molecules get hotter?
They are broken down. Cells can make certain molecules.
