How many calories are released when 6 grams of 100°C steam turns to 0°C ice?

Physics

maks197457 [2]3 years ago
6 0

Answer: 4276.2 calories

Explanation:

Given

mass of steam is 6 gm at 100^{\circ}C

Conversion of steam to ice involves

  • steam to water at 100^{\circ}C
  • water at 100^{\circ}C to water at 0^{\circ}C
  • water to the ice at 0^{\circ}C

Calories released during the conversion of steam to water at 100^{\circ}C

E_1=mL_v\quad [L_v=\text{latent heat of vaporisation}]\\E_1=6\times 533=3198\ cal.

Calories released during the conversion of water at 100^{\circ}C to water at 0^{\circ}C

E_2=mc(\Delta T)\quad [c=\text{specific heat of water,}1\ cal./gm.^{\circ}C]\\E_2=6\times 1\times 100=600\ cal.

Calories released during the conversion of water to the ice at 0^{\circ}C

E_3=mL_f\quad [L_f=\text{latent heat of fusion}]\\E_3=6\times 79.7=478.2\ cal.

The total energy released is

E=E_1+E_2+E_3\\E=3198+600+478.2=4276.2\ cal.

Hey!!

here is your answer >>>

We know that, acids and strong bases are good conductors of electricity!. And gold conducts electricity , while the best is silver and niext comes gold!. And H20 which is water contains less ions , so it is not a good conductors , it is a conductors but not a good conductor!. Salt in it's solid for cannot produce ions, hence, it cannot conduct electricity , but when this salt is mixed with water or when it is in it's molten state it can conduct electricity!. So now,the answer for the question is ,

B) III and IV only!.

Hope my answer helps!
