Put a thermometer in the water and wait until it boils. When it boils record the temperature and compare it to the normal water boiling point.
In liquids, particles are slightly spaced from each other and move around somewhat freely, but still bump into each other. Gases on the other hand move randomly and rarely bump into each other, thus they are more spaced out.
If it is shown as ∆H , then it means that a specific chemical reaction is undergoing heat in Kelvin(K). If it is shown as ∆H° , then it means that a specific chemical reaction is undergoing heat in Celsius(C⁰).
Hope this is the answer you are looking for mate!

Answer:
The given metal is beryllium.
Explanation:
Given data:
Mass of metal = 74 g
Volume of metal = 40 cm³
Which metal is this = ?
Solution:
First of all we will calculate the density.
it is mass divided by volume.
d = m/v
d = 74 g/40 cm³
d = 1.85 g/cm³
In literature it is given that the density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
