Question

a mixture of a certain of milk with 60 L OF WATER is worth rs.10 L .if pure milk worth rs. 40 l how much milk is there in the mixture

Answer 1

Step-by-step explanation:

Specific heat capacity . Defined as the energy needed to raise the temperature of 1 kg of substance by 1 K. Example 3: 0.5 kg of water is heated from 10 °C to 100 °C. How much does its internal energy rise? Rise in temperature =100* C-10* C=90* C This is also a rise of 90 K (C and K are the same size) Delta*U = mc * Delta * T; =0.5 kg*4200 J kg^ -1 K^ -1 *90 K; =190000 J. Measuring specific heat capacity An experiment can be done to find the specific heat capacity using an emersion heater.
