What happens to the thermal energy of an object as temperature decreases as it increases?
it decreases because when an object is moving as the temperature decreases the object decreases
The pressure of gas decreases with increasing temperature?
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
Does kinetic energy increase with increasing temperature?
It's more like temperature increases with increasing kinetic energy. In science, temperature is a measure of the average kinetic energy of a system. As a substance is heated it's particles move faster, increasing their kinetic energy, and this causes a rise in temperature.
Why is it important to lower activation energy?
ITs important becayse enzymes allow chemical reactions to occur at the normal body temperature
What is the minimum amount of energy required for two substances to react?
The minimum amount of energy needed is called the "activiation energy". It varries depending on factors such as your reaction, temperature and several others.
Why does increasing the temperature speed up the reaction?
It provides energy to overcome the activation energy.
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.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
How does activation energy affect the length of a reaction?
as activation energy decreases, reaction will finish faster (length of reaction decreases)
What is a substance that decreases activation energy?
A catalyst
How do enzymes affect activation energy and reaction temperature?
As kinetic energy, and therefore temperature increases, the number of effective collisions which result in sufficient activation energy also increases, which is why reactions happen at a faster rate at higher temperatures.
What happens when activation energy is in presence of an enzyme?
the energy decreases
What is the effect of a catalyst on the required energy to achieve effective collisions?
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction
Which has higer rate of reaction the one with higher temperature or not?
The greater the temperature, the faster the rate of reaction. This is due to the fact that increasing temperature increases the activation energy, which is the amount of energy needed to get a reaction started.
Why does increasing the temperature of a reaction increase its rate?
It provides energy to overcome the activation energy.
What can decreases the activation energy needed to start a reaction?
a catalyst
What do you call the kinetic energy needed for molecules to chemically react?
The minimum amount of kinetic energy needed by the reactant molecules to react is the activation energy. If the energy of the reactants are less than that, they wont react.by increasing the temperature, the activation energy of reactants can be increased.
