Question

hello everyone!!
Try my question...

● The amount of heat required in converting 1g ice at -10°C into steam at 100°C will be:-

1)3028J
2)6065J
3)721J
4)616J

Answer 1

Hey mate!!
_____________★_★

★ Conversion ↓↓


1g ice (-10℃) → ICE (0℃) → WATER (0℃)

→ WATER(100℃) → STEAM(100℃)

★ LATENT HEAT FPR FUSION = 330J/gm

★ LATENT HEAT FOR VAPORIZATION = 2230 J/gm

→ now,

Q(heat) released =

0.5 × 4.2 + 330 + 420 + 2230 = 2982.1

approximation taken..

so, your answer is option 1) 3028J

hope it helps!!

Answer 2

Hi mate,

here basically you have to find heat required for ice to convert to water then water at 0 ° C to water at 100°C and then water at 100°C to steam.

Thank you
