Answer:
I think it is the second one
Explanation:
Because what the cold water did to the table salt, is that it separated its molecules dissolving the salt.
even though the rock salt was in hot water it was a bigger particle. But the big difference was only because the water temperature ️.
Explanation:
potential energy is the correct answer
K2 SO4 = 2[K+] + [SO4 2-]
Which means that every mol of K2SO4 gives 3 moles of ions.
Then 1.25 mol of K2SO4 gives 3*1.25 = 3.75 moles of ions.
Answer: 3.75
Answer: The final volume decrease with an increase in pressure at constant temperature
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to the volume of a gas at constant temperature and constant number of moles.
where,
= let initial pressure of gas = p
= final pressure of gas = 2p
= initial volume of gas = v
= final volume of gas = ?
Now put all the given values in the above equation, we get:
Thus the final volume decrease with an increase in pressure at constant temperature
