Answer:
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
Answer:27,430J/g.K
Explanation:q= mass* specific heat capacity * change in temperature (kelvin)
22*4.184*[(100-25) + 273]
22*4.184*298
27,430J/g.K
