Which is true of a melting point and a boiling point? a. the melting point is a higher temperature than the boiling point. b. the melting point is a lower temperature than the boiling point. c. the melting point and the boiling point depend on the size of the sample.

B - The melting point is a lower temperature than the boiling point.

Step-by-step explanation:

Melting point is the temperature at which any given solid will melt. The state of the solid changes from solid to liquid.

Boiling point is the temperature at which a given liquid boils and changes to vapor state. Like water starts to boil at 100 degrees Celsius.

The boiling point of a substance cannot be lower than its melting point.

So, the answer here is - The melting point is a lower temperature than the boiling point.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
