Is density affected by temperature

Answer 1

Yes, see the table for air. Table - Density of air ρ vs. temperature °C

Effect of temperature

°C ..... ρ in kg/m3

−10 ..... 1.342

.− 5 ..... 1.317

....0 ..... 1.292

.+ 5 ..... 1.269

+10 ..... 1.247

+15 ..... 1.225

+20 ..... 1.204

+25 ..... 1.184

+30 ..... 1.165 Air at 0 degrees Celsius has a density of 1.292 kg/m3 = 1.292 g/L = 0.001292 kg/dm3 = 0.00001292 kg/L = 0.00001292 g/cm3 = 0.00001292 g/mL.

Answer 2

Yes, the density of a substance changes if you modify its temperature or pressure because both will cause it to expand or contract and therefore modify its density. To make sure there is no confusion, it is best to note that its mass stays the same.
Yes. The hotter matter becomes, the more it expands or: "The more heat is applied to a body, the more its density will decrease." This is commonly explained by the body's particles to convert the gained thermal energy into kinetic energy. Their increased movement causes the body to expand.

Water however is famous for being an exception to this rule. It reaches its highest density at about - 3.98 degrees Celsius and expands from freezing point to then. This is what causes the Anomalies of water.

Normal fluids gradually gain volume when heated, or lose volume when losing heat.

This effect is stronger, the lower the starting density. Thus it can be easily observed with gases and to an lower extent in fluids and solid bodies.

Answer 3

The density of a substance can be altered by temperature. As a substance is heated, its molecules gain more kinetic energy and take up more space. Same mass taking up more space equals lower density.

Answer 4

Temperature often affects the volume of something, and that would affect the density. However, if you put a gas in a sealed container, you could raise the temperature without affecting the density.

Answer 5

Many solid substances will expand/contract with temperature change. If it expands, then the volume increase, while the amount of substance remains constant, therefore the density decreases (volume is in the denominator of density formula) If it contracts, then the density increases.

Answer 6

As temperature increases in fluids, density decreases, besides the substance water which has its highest density at its liquid form( ice floats on water).

Answer 7

density decreases as temperature increases.

Answer 8

Yes it is because usually the hotter the temperature the less dense some metals are.
