How do changes in temperature affect the rate of a reaction?
An increase of temperature increase the rate of a reaction.
How do changes in temperature and energy influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
What changes could you use to increase the atom economy in a reaction?
Addition of a catalyst or increasing the temperature will increase the rate of a chemical reaction.
What is the dependent variable that shows how the volume of gas changes with changes in temperature?
The volume of gas
Why the temperature be constant n nernst distribution law?
Might be possible that the solubility may increase of the solute in the solvent and its concenteration may changes.
What happens to volume as temperature changes?
if volume of a gas increases temperature also increases
How the temperature of water changes when sugar is added to it.?
The temperature increase a bit.
How does an increase in temperature account for the fact that substances change state?
An increase in temperature changes the state because it melts it
How with temperature changes solubility of gases?
The solubility of gases increase at low temperature.
When solid changes to liquid rise in temperature or drop in temperature?
Melting need an increase of the temperature.
How do changes in temperature affect the rate of a reaction?
An increase of temperature increase the rate of a reaction.

What effects does temperature have on chemical changes?
Generally the speed of reaction increase when the temperature is increased.
What are the changes that increases pressure?
- a decrease in volume- the increase of temperature
What radioisotope is used to detect changes in bodily functions?
Tracer
What happens to volume during phase changes?
Volume increases with increase in temperature, and decreases with decrease in temperature.
