It is changing from a solid to a liquid, which is a physical change.
Did any properties change? Does it still look like cheese, taste like cheese??
So this is only a physical change.
Melting is a physical change. The identity of the substance does not change, but the physical state of the substance changes.
yes, melting is a physical change. You are turning a solid (cheese) into a liquid.
It is a Chemical Change
melting is a physical change
Melting is a physical process.
Chemical
no
No it's a chemical change as you can't 'untoast' the bread.
A physical change could be easily described as a change that you can reverse. Melting an ice cube, than freezing it, etc. Eating is actually both because you chew the food and swallow it. After that your stomach's enzymes dissolves the food and readies it for your digestive system. :D
chemical reaction.
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
Yes. It still has cheese, which is a dairy product.
It is a chemical change - oxidisation.
No, its a physical change. It make be changing from a solid to a liquid, but it is not changing at a chemical level, only at a physical level. No matter how you slice it, it is still ice cream (but maybe a little drippy).
No it's a chemical change as you can't 'untoast' the bread.
It depends what kind of cheese and by cheese i mean brand. mm.. usually a slice of cheesdale cheddar cheese is 21g.. with 3.65g protein =)
Sliced cheese has fat.
Usually about 79 calories in 0.7 oz or 20g slice of processed cheese to 110 calories in slice of white processed cheese.
would you use kilograms or grams to measure the mass of a slice of cheese
How can you define a " slice" . I could slice thin or thicker. Even companies that sell sliced cheese do not all use the same thickness.
The general census is about 1g of carb per slice of cheese. : )
There is no answer to this, as a person can slice cheese as thick or as thin as they like, and the piece of cheese they slice it from can be of any height or any length.
Most cheese slices can have anywhere from about 70-120 calories per slice, depending on the type of cheese and the brand.
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.
