An unknown mass of water (m1) of temperature 3.4°C is mixed with another unknown mass of water (m2) of 55.6°C. The combined mixture of water (m3) has a temperature of 26.1°C and a mass of 154 grams. Determine the mass of (m1) and (m2) WITHOUT using c_water= 4184 J/kg°C.

Expert Solution

we can use law of calorimetry i.e.

if the temperature before mixing is = T1 & T2
And temperature after mixing = T
Than
And
putting the values
given , T1 = 3.40c , T2 = 55.60c , T = 26.10c
.................(1)
and also given that
.........................(2)
putting the value of m2
...................answer.

An object of mass m1 approaches with velocity v1 another object of mass m2, which is at rest, next to a spring having force constant k. The spring is fixed to a wall and m2 can compress the spring. This is one-dim horizontal collision without friction. We consider two collision scenarios, one which is perfectly inelastic, and the other which is elastic. (a) In the first collision case the object m1 strikes m2 and sticks. Moving together, they compress the...

3 Kg mass of water is heated to a temperature of 99.5 C at 1 bar of pressure. It is slowly poured into a heavily insulated beaker containing 7.5 Kg of water at a temperature and pressure of 4 C, 1 bar, respectively. The specific heat of the water, an incompressible material is, c = 4.1 KJ/(Kg K). The beaker can be considered to be an adiabatic system. The two water mass’ reach an equilibrium temperature. There is no kinetic...
