What is the Kelvin temperature of a substance directly proportional to?
There is no simple answer to how temperature is defined at the microscopic level. However, though this is not entirely accurate, it helps to think of temperature as the average kinetic energy of the particles.
Why a solid substance melts to liquid at high temperature?
the possibility of a solid substance to melt depends on the bond present in the solid substance.at high temperature,most or some of the bonds present in the substance break,leading to vibration of the crystal lattice present in the substance,if the vibration within compound increase,there is a distortion and breaking down of the bonds present,making the solid substance attain a more stable state,that is in liquid form.
Does density of a substance generally decrease while the temperature increases?
No, the density of most substances typically decreases as the temperature increases. This is because the increase in temperature generally leads to an increase in the average kinetic energy of the substance's particles, causing them to move faster and occupy a larger volume. As a result, the density, which is defined as mass divided by volume, decreases. However, there are some exceptions, such as water, where the density increases between 0°C and 4°C due to changes in the structure of the water molecules.
What is the most common unit used to report the solubility of a substance?
Degress Celsius and grams of solute/100g of water
If a substance is not at its melting or boiling point as the heat content of a sample of matter increases what happens?
As the heat content increases, the temperature of the substance will rise. However, if the substance is not at its melting or boiling point, it will not undergo a phase change. Instead, its temperature will continue to increase until it reaches its melting or boiling point, at which point a phase change will occur.
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
If the temperature is increased the rate of most reactions will?
The rate of most will also increase.

Which would burn the most 100g of water at 100 degrees or 100g of steam at 100 degrees?
100g
Explain how a global temperature increase could affect plants?
A small increase in temperature may help some plants, but will be damaging to others. A large increase in temperature will kill most plants.

How do you quicken evaporation?
Evaporation is a function a substance's vapor pressure. There are two ways to increase the rate of evaporation. If you raise the temperature for most substances it evaporates more quickly. If you give it a larger surface area it will also evaporate more quickly.
What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
When the temperature of a substance decreases significantly most substances will contract.
What is the most common unit used to report the solubility of a substance?
Degress Celsius and grams of solute/100g of water
What happens to the solubility of most solutions if the temperature increase?
It increases.
What happen to volume of substance when placed say in a freezer?
A number of factors have to be considered, the state of the substance, solid, gas or liquid. The condensation and freezing point of the substance. The temperature inside the freezer. The pressure Most, but not all, substances reduce in volume and increase in density when cooled. Water for instance, reduces in density when frozen.
