increases
Raising the temperature the density is lowered.
The density will decrease because the heated metal contracts and its particles slow down.
When the air inside a balloon is heated, its density decreases. This happens because the air molecules gain energy and move farther apart, resulting in a decrease in the air's density.
It is reduced by haft
Generally, the density of solids, liquids, and gases decreases as they are heated. When heated, the particles in these substances gain energy and move more, causing the substance to expand, which leads to a decrease in density.
When rubber is heated, it typically expands and its density decreases. This is because the increased thermal energy causes the rubber molecules to vibrate more, creating more space between them and leading to a decrease in density.
When a gas is heated, its density decreases because the particles move faster and spread out, increasing the space between them. This results in a decrease in the number of gas particles per unit volume, leading to a lower density.
when motor oil is heated it viscotity rises and becomes thicker
When oil is heated, its volume increases due to thermal expansion. This is because the heat causes the oil molecules to move faster and spread out, leading to an overall increase in volume. Additionally, the expansion of the oil can also be attributed to the decrease in its density as it becomes less dense when heated.
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
When a fluid is heated up, its density generally decreases. This is because as the temperature increases, the average kinetic energy of the fluid molecules also increases, causing them to spread out and occupy a larger volume, leading to a decrease in density.
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.
