What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called heat of vaporization.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
How does plants enable to trap energy from the sun?
Sunlight is needed by plants to create photosynthesis. This is how the plants collect and store energy in order to thrive and grow, The sunlight is converted to energy that the plant needs.
How much heat does methane trap?
It is not clear what you mean by 'trap'. It contains chemical energy which can be released by burning, giving 55.5 MJ per kg. You may however be referring to the ability of the substance to absorb heat, i.e. its heat capacity. This is the amount of energy absorbed when the temperature of the substance increases by 1 degree Kelvin. This is 2.087 kJ/kgK at 200 K. (It varies a little with temperature.)
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called heat of vaporization.
This substance can trap light energy and convert it to chemical energy?
Chlorophyll is the substance responsible for trapping light energy in plants through the process of photosynthesis, where it converts this energy into chemical energy in the form of glucose.
What is the equation to work out the amount of energy needed to change state?
The equation to calculate the amount of energy needed to change state is: Q = m * L, where Q is the energy needed, m is the mass of the substance, and L is the specific latent heat of the substance.
What term describes a substance that lowers the energy needed to start a chemical reaction?
This substance is a catalyst.
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
What is a substance that your body stores energy as?
One substance that the body stores energy as is glycogen, which is a complex carbohydrate stored in the liver and muscles. When needed, glycogen can be broken down into glucose for energy.
What most influences the amount of energy needed to change the temperature of a substance?
The amount of energy needed to change the temperature of a substance is most influenced by its specific heat capacity, which is the amount of energy required to raise the temperature of a given mass of the substance by 1 degree Celsius. Substances with higher specific heat capacities require more energy to change temperature compared to those with lower specific heat capacities. Additionally, the mass of the substance being heated also plays a role in determining the amount of energy needed.
What term describes a substance that lowers the amount of energy needed to start a chemical reactions?
Catalyst
What term describe a substance that lowers the amount of energy needed to start a chemical reaction?
Catalyst
What best describes the enthalpy of formation of a substance?
The energy change that happens when a substance forms from its elements (APEX)
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
