A hot liquid at 80 ̊ C is added to 600 g of the same liquid originally at 10 ̊ C. When the
mixture reaches 30 ̊ C, what will be the total mass of the liquid?

you have been asked to design an appliance for a water supply pumping station. The appliance will operate using a tree plantation as a starting source of energy the following supplies only;a steam-powered electric generator, water pump and a light-activated siren system. Use a flow chart of 7[seven] items only to describe the sequential energy conversions to be anticipated.

A mass of ideal gas of volume 400 cm3 at a temperature of 27 ˚C expands adiabatically until its volume is 500 cm3. Calculate the new temperature. The gas is then compressed isothermally until its pressure returns to the original value. Calculate the final volume of the gas. Assume γ = 1.40.

A current of
0.2 A
goes through an electric motor for
6 min.
How many coulombs of charge flow through it during that time?

Heat flow through a wooden board 30mm thick at 0.0086w/cm^3 when one of its side 20°C warmer than the other. Determine the thermal conductivity of the wood.

A faulty mercury in glass thermometer indicate that the ice point of pure water is 0.8°c and steam point is 99.5°c under standard atmospheric pressure.Deduce an expression in the form of y=mx +c,where m and c are constant to relate the faulty temperature reading F°c to the correct temperature T°c

A woman is unhappy with the rate at which eggs cook in a saucepan of boiling water. State
in 2 words only, the method she could use to get the eggs to cook fastest.

One end of a uniform well lagged metal bar of length 0.8m and crossectional area of 4.0×10^-3m^2 is kept in steam at 100°c while the other end is melting in a well lagged container.The ice melt at a steady rate 5.5×10^-4KGS^-1 and the thermal conductivity of material of the bar is 401Am^-1k^-1.calculate the specific latent heat of fusion of ice
