Answer:
Fahrenheit
Explanation:
Scientists would use Kelvin, and occasionally, Celsius scales. They do this because they need a scale that goes Sub-zero. Sub-zero temperatures are below 0° centigrade or, in the United States, below 0° Fahrenheit.
They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance
Explanation:
no. of molea of Ca(NO3)2 = given mass/molar mass
no. of moles= 92/ 164 = 0.56 mol
formula=
Molarity = moles of solute /solution in litres
Molarity = 0.56/ 0.4
=1.4 M
