The density of water at `4^0C` is supposed to be `1000 kg m^(-3)`. It is same at the sea level and at a high altitude?

The density of water at 0^@C is 0.998 g cm^(-3) at 4^@C is 1.00 g cm^(-3) . Calculate the average coefficient of volume expansion of water in the temperature range 0^@C to 4^@C .

calculate the increase in internal energy of 1 kg of water at 100^(o)C when it is converted into steam at the same temperature and at 1atm (100 kPa). The density of water and steam are 1000 kg m^(-3) and 0.6 kg m^(-3) respectively. The latent heat of vaporization of water =2.25xx10^(6) J kg^(1) .

Density of mercury is 13600 kg m^(-3) . Calculate the relative density.

The speed of sound in hydrogen at 0^@C is 1280 m s^(-1) . The density of hydrogen at STP is 0.089 kg m^(-3) . Calculate the molar heat capacities (C_p and C_v) of hydrogen.

The density of water at 20^@ is 998 kg//m^3 and at 40^@ 992kg//m^3 The coefficient of volume expansion of water is

An ice cube floats on the surface of water filled in glass tumbler (density of ice =0.9 g//cm^(3)). Will the water level in the glass rise? When the ice melts completely (AS_(1))

Read the paragraph and answer the following question: You must be knowing about the high and low tides that occur regularly in the sea. The level of the sea water at any given location along sea shore increase and decreases twice a day at regular intervals. High and low tides occur at different times at places. The level of water in sea changes because of the gravitational force exerted by the moon. Water directly under the moon gets pulled towards the moon and the level of water there goes up causing high tide at that place. At two places on the earth at 90^(@) from the place of high tide, the level of water is minimum and low tides occur there. How many times the sea level at the coast change?

0.1 m^(3) of water at 80^(@)C is mixed with 0.3 m^(3) of water at 60^(@)C . What is the final temperature of the mixture ?
