Raising the temperature the density is lowered.
The density of air when it is heated decreases
It's density will decrease.
The density will decrease because the heated metal contracts and its particles slow down.
Density remains unchanged.
Its density increases.
Density will decrease. When a quantity of air is heated, it expands giving it a larger volume. It will still have the same mass, so the density will be lower.
Density = Mass / Volume The amount of matter in the balloon does not change when it is heated and the volume doubles so the result is the density is halved.
Temprature affects the volume, since most objects expand when they are heated. And density is mass / volume.
gets lighter, thinner, by expanding.
The density of the gas sample that is heated the density decreases. Cohesive forces in matter are related to potential energy from particle attractions.
Its density decreases.
Equilibrium. (It neither rises nor sinks.)
Mostly it decreases because it expands, but it is not universally true.
It usually becomes less dense. Ice is an exception.
In almost all cases, the matter expands. Density = mass / volume. When volume increases, the density decreases, because the mass is fixed.
Solid objects may melt into a liquid form when they are heated. Liquids may become gases when heated. When objects are combined and heated, they can become new objects altogether, like in cooking.
In almost all cases, matter expands and becomes less dense when it is heated. Melting ice is an exception.
The density of heated air is less than the density of cooler air.
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
If an objects density is less than the density of what it is put in it will float. If the objects density is greater it will sink.
Objects whose density is lower than the density of the fluid they're in float. Objects whose density is higher than the density of the fluid they're in don't.
If an object is heated, its atoms get more of kinetic energy, so they collide faster and thus volume is increased and desity is decreased.
The volume of a substance increases when heated, causing a decrease in density.
An objects density is determined by its' weight and volume.
