Answer:
Explanation:
Volume of metal = volume of water displaced = (30.0 - 25.0) ml = 5.0 ml
Density of metal = 5.50 g/ml
Mass of metal =
Volume of water = 25.0 ml
Density of metal = 1.0 g/ml
Mass of metal =
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of metal = 27.5 g
= mass of water = 25.0 g
= final temperature = ?
= temperature of metal =
= temperature of water =
= specific heat of lead = ?
= specific heat of water=
Now put all the given values in equation (1), we get
Thus the specific heat of the unknown metal sample is

Answer:
It is an example of ionic compound and ionic salt
The answer is A. They actually have negligible mass because gamma rays are photons with very high frequency. Gamma rays are the strongest in the electromagnetic spectrum meaning they have the highest energy. This way, they also have very low frequency hence have lower chances of interacting with matter thence more easily able to penetrate solids.
