In an experiment to determine the specific latent heat of vaporization of water steam 100 degrees Celsius was passed into water contained in a well lagged calorimeter the following measurements were made mass of calorimeter 60 grams initial mass of water 8 grams final mass of calorimeter + condense steam 143 initial temperature of mixture 17 degrees celcius final temperature of mixture 32 degrees Celsius specific heat capacity of copper 390 joules per kilogram per Kelvin a)determine the mass of condensed steam ​
b)determine the heat gain by calorimeter and water
c)determine the latent heat of vaporization of steam

Assuming weightless pulleys and 100% efficiency, what is the minimum input force required to lift a 120 n weight using a single fixed pulley?

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
