A 100 g glass container is at 10.0 °C. 200 g of water at 90.0 °C is added to the glass container. What is the final temperature of the water and the glass, in °C? (specific heat of water = 1.00 cal/g °C, specific heat of glass = 0.200 cal/g °C)

To solve this problem, we need to use the principle of conservation of energy, which states that the total energy in a closed system is constant. In this case, the energy gained by the glass container is equal to the energy lost by the water.

First, let's calculate the energy gained by the glass container when its temperature increases from 10.0 °C to the final temperature (Tf). The formula to calculate the heat gained or lost is Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the change in temperature.

For the glass container: Qglass = mglass * cglass * (Tf - Tglass_initial)

Next, let's calculate the energy lost by the water when its temperature decreases from 90.0 °C to the final temperature (Tf).

For the water: Qwater = mwater * cwater * (Twater_initial - Tf)

Since the energy gained by the glass is equal to the energy lost by the water, we can set these two equations equal to each other and solve for Tf.

mglass * cglass * (Tf - Tglass_initial) = mwater * cwater * (Twater_initial - Tf)

Substituting the given values:

(100 g * 0.200 cal/g °C * (Tf - 10.0 °C)) = (200 g * 1.00 cal/g °C * (90.0 °C - Tf))

Solving this equation will give us the final temperature Tf.

To solve this problem, we need to use the principle of conservation of energy, which states that the total energy in a closed system remains constant. In this case, the energy gained by the glass container must be equal to the energy lost by the water.

First, let's calculate the energy (Q) gained by the glass container using the formula:

Q = mcΔT

where: m is the mass of the object, c is the specific heat capacity of the material, and ΔT is the change in temperature.

For the glass container: m = 100 g, c = 0.200 cal/g °C, and ΔT = T_final - T_initial = T_final - 10.0 °C.

So, Q_glass = 100 g * 0.200 cal/g °C * (T_final - 10.0 °C).

Next, let's calculate the energy lost by the water using the same formula:

For the water: m = 200 g, c = 1.00 cal/g °C, and ΔT = T_initial - T_final = 90.0 °C - T_final.

So, Q_water = 200 g * 1.00 cal/g °C * (90.0 °C - T_final).

Since the energy gained by the glass container is equal to the energy lost by the water, we can set the two equations equal to each other and solve for T_final:

100 g * 0.200 cal/g °C * (T_final - 10.0 °C) = 200 g * 1.00 cal/g °C * (90.0 °C - T_final).

Solving this equation will give us the final temperature of the water and the glass.
