What else can I help you with?
What word means A substance that can cause something to happen faster than it might have otherwise but is not permanently changed itself?
That is the definition of a catalyst.
What happen in terms of kinetic theory when you heat a substance?
When you heat a substance, its kinetic energy increases, causing the particles to move faster and further apart. This leads to an increase in the substance's temperature and potentially a change in state, such as melting or boiling.
Predict what will happen to the state of the substance the atomi and molicular activity?
As the substance undergoes an increase in temperature, its atomic and molecular activity will also increase. This will result in the particles moving faster and having more energy, potentially leading to a change in state if the substance reaches its melting or boiling point.
What can you do if you want to either make a chemical reaction happen faster or slower?
to slow down a chemical reaction you use the substance called an inhibitor. to speed up a chemical reaction you use the substance called a catalyst.
What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
What word means A substance that can cause something to happen faster than it might have otherwise but is not permanently changed itself?
That is the definition of a catalyst.
What enzymes in saliva help our bodies break down food faster. A substance that make reactions happen faster is called?
The enzyme in saliva is amylase.A catalyst make a reaction happen faster.
A substance which helps make a chemical change happen but is not changed itself in the process is called an?
The answer is catalyst
What is a substance which helps make a chemical change happen but is not changed itself in the process is called?
Catalyst: a substance which speeds up a chemical change or enables the change to take place at a lower tempature, and is not changed or used up in the reaction.
What is the two ways of making evaporation happen faster?
To make evaporation happen faster, you can increase the temperature of the substance being evaporated, which provides more energy for the molecules to escape into the air. You can also increase air circulation around the substance to remove the evaporated molecules quickly, allowing more molecules to escape into the air.
What happen in terms of kinetic theory when you heat a substance?
When you heat a substance, its kinetic energy increases, causing the particles to move faster and further apart. This leads to an increase in the substance's temperature and potentially a change in state, such as melting or boiling.
Is there any way to make time go faster BESIDES knowing that something you dread is going to happen?
no there is not
What happen to the molecules when a substance changed state from a liquid to a gas?
They move freely in all directions (except collisions), no forces between each other
What happen to the heat energy as a substance solifies?
what happen to the heat energy as a substance solidifies
What two things happen to particles in a substance when the substance is heated?
When a substance is heated, the particles gain energy and vibrate faster, causing the substance to expand. As the temperature increases further, the particles can reach a point where they break free from their fixed positions and transition from a solid to a liquid state.
What can happen to sound energy travelling through the air when it meets a new substance?
When sound energy meets a new substance, three things can happen: reflection (bouncing off the substance), absorption (being absorbed by the substance and converted into another form of energy), or transmission (passing through the substance). The extent to which each of these occur depends on the properties of the substance and the frequency of the sound wave.
Predict what will happen to the state of the substance the atomi and molicular activity?
As the substance undergoes an increase in temperature, its atomic and molecular activity will also increase. This will result in the particles moving faster and having more energy, potentially leading to a change in state if the substance reaches its melting or boiling point.
