Answer : The molar heat capacity at constant volume and constant pressure is 29.9 J/mol.K and 38.2 J/mol.K respectively.
Explanation :
Formula used for specific heat at constant volume :
where,
= heat = 229 J
n = moles of gas = 3.0 mol
= molar heat capacity at constant volume = ?
= change in temperature = 2.55 K
Now put all the given value in the above formula, we get:
The molar heat capacity at constant volume is 29.9 J/mol.K
Now we have to calculate the molar heat capacity at constant pressure.
Formula used :
where,
= molar heat capacity at constant volume = 29.9 J/mol.K
= molar heat capacity at constant pressure = ?
R = gas constant = 8.314 J/mol.K
Now put all the given value in the above formula, we get:
The molar heat capacity at constant pressure is 38.2 J/mol.K

Answer: star
Exoplanets are the planets present in the other star system. There are billions of stars in our galaxy and we expect presence of other planetary systems similar to our solar system. Exoplanets can be detected by a) radial velocity method b) astrometric method c) transient method. In the radial method, we observe the changes in the spectrum of the light coming from star when an exoplanet is orbiting it. There is change in gravitational pull as the planets goes around the star. It sometimes pulls into smaller orbit. like this the star wobbles back and forth. By measuring the blueshift and redshift in the star's spectrum, exoplanet can be discovered.
Answer:
Metabolism
Explanation:
The sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.
When an iron is dipped in Copper Sulphate
Solution this reaction between them and
copper sulphate change into blue color to light
green color. This show that iron is more
reactive then copper, it can to replace copper
from CuSO4 , CuSO4 is of blue color and
FeSO4 is light green color.
Hope it helps
