Please Kindly Help me to answer this. Thank you very much! Note: Round off your final answer to the nearest ten-thousandth.  Take note: Only the final answer should be rounded off. Do NOT write answers in scientific notation. Always write the answer with 4 decimal places, (i.e, 4.25 should be written as 4.2500) EXCEPT for whole numbers. Question: The minimum amount of heat required to completely melt 130 g of silver initially at 16.0 °C is ______ kJ. Assume that the specific heat does not change with temperature.

students of physies Question: Suppose 1st year wish to find the weight- to a hill. dept- go They of the hill using theire thermodynamic knowledge. At top of the hill the Boiling point of water is Pressure variation is governed 90'c . Pu= Povo by where Po is the sea level pressure, 101kpa кра and latent heat of vaporization Norma) B.P is 100'C. is 2257 kJ/kg. g= 9.8) ms². Calculate the weight- of the hill.
