Is a fridge door going rusty a chemical or physical change?
The formation of rust is a chemical change because the steel (iron) in the door has reacted with oxygen in the air to form a new substance called rust, which has properties different from the iron and the oxygen that reacted.
What happens to a balloon's pressure when put into the fridge?
it dies
Why store DNA in refrigerator until testing?
Keeping things cool slows down reactions. For example you put meats and high risk foods in the fridge to slow down the bacteria and to prevent the action of microbes. Like in science to make a reaction happen faster you add heat to it, but this causes the reaction to happen faster but it also causes the unwanted reactions to happen faster, that's why people use a catalyst. But putting things in the fridge slows down these reactions and preserves them for later use.
Why controlling reaction rates are important to your daily life?
Rate of reactions are used in many things in daily life. For example; - Enzymes: Enzymes are biological catalysts (substances with increase the rate of reactions). They quicken the rate at which food is broken down. - Washing Clothes: Temperature affects the rate of reactions. The higher the temperature the quicker the particles move. If they move quicker there is a bigger chance that they will collide (search the collision theory). This is why the temperature at which clothes are washed is important. There are enzymes in washing powder. They work well at a certain temperature, but when the temperature gets too hot, they do not work. The proteins that make up the enzyme are "denatured". (search how enzymes work) - Fridges Again, at a lower temperature the rate of reaction is less. So in a fridge reactions happen slower so foods rot slower (as rotting is also a chemical reaction) Hope this helps! I looked on the internet for this question too, but it doesn't help. I found these answers in the Chemistry for You book by Lawrie Ryan. They're really useful.
What happens when a sample of water turns into ice?
it will froze and if you leave i like that and if you don't put in in the fridge it will melt
Why do mint leaves turn black in the fridge?
Mint leaves turn black in the fridge due to oxidation, a chemical reaction that occurs when the leaves are exposed to air. This reaction causes the leaves to darken in color and lose their freshness.
Can you have an allergic reaction to eating water chestnuts stored in can in fridge?
If it's really an allergic reaction, it wouldn't matter if they were stored in the fridge. Just the food would cause the reaction. It's not a good idea to store anything in an opened can. The metal in the can causes reactions with some foods when air is introduced and it's possible that some of the reactions are toxic. If you have left over food from a can, transfer it to glass or plastic for storage.
Would putting epoxy resin in the refrigerator affect it's rate of curing?
Yes, indeed. Epoxy resin cures by chemical reaction. Any chemical reaction is speeded up when you heat it, but when you cool it in the fridge, the reaction slows way down!
What are real life examples of enthalpy?
Burning of natural gas, evaporation of water, and formation of bonds in chemical reactions are all examples of processes that involve enthalpy changes.
What happens if you put your xbox in the fridge?
It will kill it.
Is a fridge door going rusty a chemical or physical change?
The formation of rust is a chemical change because the steel (iron) in the door has reacted with oxygen in the air to form a new substance called rust, which has properties different from the iron and the oxygen that reacted.
What happens to refrigerated crusha?
What happens if I drink CRUSHA without putting it in the fridge
What happens when we left thermometer in the fridge?
Nothing will happen, except the thermometer will show the fridge's interior temperature.
What happens to a balloon's pressure when put into the fridge?
it dies
When a fridge door goes rusty you can tell it is a chemical change because?
The fridge reacts with oxygen in the air, therefore creating rust. An example of a chemical property is ability to react with oxygen.
When does a chemical reaction take place?
A chemical reaction occurs when the conditions for a chemical reaction exist. Which is a really lame answer, so let's play with it. You want to make some water and carbon dioxide. You have some hexane, which is C6H14. If you set the hexane on fire, it will react with the oxygen in the air to produce carbon dioxide and water.
What happens after you have stopped exercise?
You crawl to the fridge and get a cold beer.
