Answer:
Total energy is constant
Explanation:
The laws of thermodynamics state that thermal energy (heat) is always transferred from a hot body (higher temperature) to a cold body (lower temperature).
This is because in a hot body, the molecules on average have more kinetic energy (they move faster), so by colliding with the molecules of the cold body, they transfer part of their energy to them. So, the temperature of the hot body decreases, while the temperature of the cold body increases.
This process ends when the two bodies reach the same temperature: we talk about thermal equilibrium.
In this problem therefore, this means that the thermal energy is transferred from the hot water to the cold water.
However, the law of conservation of energy states that the total energy of an isolated system is constant: therefore here, if we consider the hot water + cold water as an isolated system (no exchange of energy with the surroundings), this means that their total energy remains constant.

Answer:
it will be curved as in deceleration
Explanation:
Answer:
Cs=912.6J/kg/K
Explanation:
Sum of Heat gained=sum heat lośs
Definition of terms
Ms=mass of substance 0.11kg
Cs=specific heat capacity of the substance?
Ts= temperature of the substance
Tm= temperature of mixture 28.8°C
Tal= temperature of aluminium19.6°C
Tw=temperature of water 19.6°C
Mal=mass of aluminium 0.172kg
Mw=mass of water 0.148kg
Cw= specific heat capa of water 4200j/kgk
Cal=specific heat capacity of aluminium 903j/kgk
Having gotten all the parameters needed
Ms*Cs*(Ts-Tm)=Mw*Cw*(Tm-Tw) +Mal*Cal*(Tm-Tal)
0.11*Cs*(100-28.8)=0.148*4200*(28.8-19.6) +0.172*903*(28.8-19.6)
cs==((4467267)/(4895))
Cs=912.61Jkg–1K–1
