In most cases, density decreases when energy in the form of heat increases. This is why bridges and concrete sidewalks require expansion joints to prevent cracking on a warm day, for example. On the contrary, when heat energy is removed from water to it's freezing point, the density decreases when it becomes a solid (ice) as the water molecules form a solid structure that separates them by a greater distance than liquid water. This is why ice floats on water.
What else can I help you with?
Does density increase or decrease when kinetic energy increases?
it increases
What happens to the temperature of a house as the suns radiant energy touches it?
The temperature of the house increases as the sun's radiant energy is absorbed by the building materials. This happens because the materials absorb the sun's energy and convert it into heat, raising the temperature inside the house.
What happens to the density of a fluid when it is heated up?
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.
What is the relationship between magnetic energy density and the strength of a magnetic field?
The magnetic energy density is directly proportional to the strength of a magnetic field. This means that as the strength of the magnetic field increases, the magnetic energy density also increases.
When the temperature increases what happens to the density of water?
As temperature increases, the density of water generally decreases. This is because as water molecules get warmer, they gain energy and move further apart, causing the overall density of the water to decrease.
What happens to the energy of the electrons in the orbits as the radius of each orbit increases?
What happens to the energy of the electrons in the orbits of each orbit increases
What happens to the amplitude of the wave if the energy increases?
If the energy of a wave increases, the amplitude of the wave also increases. This is because amplitude is directly proportional to energy - as energy increases, more energy is imparted to the wave causing it to oscillate with greater magnitude.
What happens to temperature of the house as the suns radiation energy touches it?
The temperature of the house increases as the sun's radiation energy is absorbed by the building materials. This absorption causes the molecules in the materials to vibrate, leading to an increase in thermal energy and temperature inside the house.
What happens to an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
What happens to kinetic energy if you move?
Increases.
When a substance melt what happens to its overall energy?
It increases
What happens to the density when heat is added?
When heat is added to a substance, it increases the kinetic energy of its particles, causing them to move faster and spread out. This leads to an increase in volume and a decrease in density since density is mass divided by volume.
