Well, the weight of the freezer will change when something is put in, but the freezing of these materials will NOT change their weight.
you freeze the substance in a FREEZER
Put it in the freezer
A chemical change occurred
Syrup has a high concentration of sugars which make it difficult to freeze. The more contaminants added to water, the lower the freezing point. So if sugar is added to water ie syrup the freezing point is less than 0 oC. Depending on the concentration of the syrup will determine if it can be frozen in a domestic freezer ~ -18 oC.
This is an experiment. it will change from liquid to solid.
It is a physical change. When the water vapour inside of the freezer turns to frost (ice), it hasnt changed the fact that it is still water, just in a different form. Therefore, this is a physical change.
If there is no overflow of water, then the container's over-all weight goes up by the weight of the fish. The weight of the water itself doesn't change.
Syrup is mostly water. More water will dissolve syrup.
No. The mass doesn't change, so the weight doesn't change either.
Water solidification means freezing, that is, it turns to ice after keeping it in the freezer for some time. But it can turn back to liquid water after being removed from the freezer. Therefore, freezing is an example of reversible change.
hot water in a freezer will get hotter depending if the freezer is turned on.
The density of maple syrup seems to be normally measured in brix with the requirement of 66 brix. For the rest of us that use density in an every day sense we use water as a density of 1 as a standard. For a gallon of maple syrup produced to standard and at room temperature the weight is about 11 lbs. Given the weight of water, given the same conditions, at 8.3+ lb/gal; the density of maple syrup would then be about 1.32.
