Asupposedly silver crown is tested to determine its density. it displaces 10.7 ml of water and has a mass of 112 g. part a could the crown be made of silver?

The volume of water displace by crown is 10.7 mL. This will be equal to the volume of crown. Mass of crown is 112 g.

Density of a substance is defined as mass of substance per unit volume. It is mathematically represented as follows:

Putting the values,

The theoretical value of density of silver is also, 1 mL is equal to thus, density will be 10.5 g/mL.

This is approximately equal to the calculated value thus, the crown is made up of silver.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
