A thermos contains m1 = 0.89 kg of tea at T1 = 31° C. Ice (m2 = 0.075 kg, T2 = 0° C) is added to it. The heat capacity of both water and tea is c = 4186 J/(kg⋅K), and the latent heat of fusion for water is Lf = 33.5 × 104 J/kg. show answer No Attempt 50% Part (a) Input an expression for the final temperature after the ice has melted and the system has reached thermal equilibrium. Part (b) What is the final temperature in Kelvin?

a)

b) 295.52K

Explanation:

a) you use the following formula:

   ( 1 )

m2: 0.075kg

m1: 0.89kg

Lf= 33.5 × 104 J/kg

Ti2= 0C=273.15K

Ti1 = 31C = 304.15K

Then, you obtain T from the formula (1):

b) By replacing the values of all parameters you obtain:

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
