Raising the temperature the density is lowered.
increases
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
Temprature affects the volume, since most objects expand when they are heated. And density is mass / volume.

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.
Expand
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.
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
