No, it is less then. Density rho = mass / Volume.
Water has a density of 1,000 kg/m3 = 1,000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL at the temperatur of 3.98 degrees Celsius.
Temperature in degrees Celsius
and the density of water:
1 ................. 999,90
2 ................. 999,94
3 ................. 999,96
4 ................. 999,97
5 ................. 999,96
6 ................. 999,94
7 ................. 999,90
You see the highest number only at 4 degrees Celsius.
Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.
When air is heated up, the molecules within the air gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure and an increase in volume.
Warm water tends to stay on top of cold water because it is less dense. When water is heated, the molecules move farther apart, making warm water less dense than cold water. This difference in density causes warm water to float on top of cold water.
Dense water sinks in comparison to less dense water.
True. As air is heated, it becomes less dense and rises above cooler, more dense air. This is due to the decrease in air density causing it to become buoyant and rise.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
The particles get further away from each other as water is heated therefore making it less dense

On heating the inter molecular space decreases. So, substance becomes less dense on heating.

convection happens because fluids become less dense and expand and riseas they are heated.
When air is heated up, the molecules within the air gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure and an increase in volume.
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
Most substances expand and become less dense when heated because the increased thermal energy causes the molecules to move farther apart, which decreases the density. However, there are exceptions such as water, which becomes denser when heated from 0°C to 4°C due to its unique behavior when transitioning from a liquid to a solid.
expand, causing the air to become less dense and rise.
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.
