Latent heat of $1\,gm $ of steam is $536 \,cal/gm,$ then its value in $joule/kg$ is
A block of ice at $-12^{\circ} C$ is slowly heated and converted into steam at $100^{\circ} C$. Which of the following curves best represents the event?
A stationary object at $4°C$ and weighing $3.5\, kg$ falls from a height of $2000\, m$ on a snow mountain at $0°C$. If the temperature of the object just before hitting the snow is $0°C$ and the object comes to rest immediately $(g = 10\,m/{s^2})$ and (latent heat of ice$ = 3.5 \times {10^5}\,joule/\sec $), then the object will melt
What are fusion and melting point ? On what does the value of melting point depend ?
Values for latent heat in Column$-\,I$ and its values are given in Column$-\,II$. Match the followings :
Column $-\,I$ | Column $-\,II$ |
$(a)$ Latent heat of vaporization $L_V$ | $(i)$ $22.6\, \times \,{10^5}\,J\,/kg$ |
$(b)$ Latent heat of fusion $L_f$ | $(ii)$ $33.3\, \times \,{10^5}\,J\,/kg$ |
$(iii)$ $3.33\, \times \,{10^5}\,J\,/kg$ |
