## How do you find the final temperature of a mixture?

Calculate the final temperature of the water mixture using the equation T(final) = (m1_T1 + m2_T2) / (m1 + m2), where m1 and m2 are the weights of the water in the first and second containers, T1 is the temperature of the water in the first container and T2 is the temperature of the water in the second container.

**What would be the final temperature of a mixture of 50 g of 20 C water and 50 g of 40 C water?**

Answer : Let the final temperature of the mixture of 50g of water at 20°C temperature and 50g of water at 40°C be T. Let the specific heat capacity of water be S. Hence, the final temperature of a mixture of 50g of water at 20°C temperature and 50g of water at 40°C temperature would be 30°C.

### What happens when two liquids of different temperatures are mixed?

Heat Transfer: The movement of heat from a warmer object to a colder one – when two substances at different temperatures are mixed together, heat flows from the warmer body to the cooler body until they reach the same temperature (Zeroth Law of Thermodynamics – Thermal Equilibrium).

**How do you calculate the final temperature of a mixture of ice and water and steam?**

During condensation, Q2=m(steam)L(heat of vaporization) is released. When the condensed steam cools down from 100 °C to the final temperature T, Q3=c(water)m(steam)(100-T) heat is released. q1=c(ice)m(ice)(0-(-40)) is the heat needed to warm up the ice to 0°C.

#### What is the final temperature of the mixture of 50g of steam?

Answer: The final temperature will be 0°C.

**What is the final temperature of the mixture of 50 g of steam?**

## When we mix water at 50 C with water at 90 C the temperature of the resulting mixture will be?

Explanation: Adding 50C to 90C means that you’re cooling down the 90C water. So all you have to do is take away 50C from 90C which leaves u with 40C.

**What is final temperature?**

Add the change in temperature to your substance’s original temperature to find its final heat. For example, if your water was initially at 24 degrees Celsius, its final temperature would be: 24 + 6, or 30 degrees Celsius.

### When hot liquid is mixed with a cold liquid what will be effect on final temperature?

When hot liquid is mixed with cold liquid, the molecules collide and transfer heat. When heat is transferred, the temperature is undefined. Once the heat energy is shared by the molecules, the system reaches equilibrium and the temperature becomes nearly constant.

**What is the final temperature of cold water?**

0ºC

The thermal energy of the warm water is not enough to melt all of the ice (only 93% of it), so the final temperature of the ice/water mixture will be 0ºC.

#### What is the final temperature of 300 grams of ethanol?

300 grams of ethanol at 10 °C is heated with 14640 Joules of energy. What is the final temperature of the ethanol? Useful Information: The specific heat of ethanol is 2.44 J/g·°C.

**What happens when you put warm metal in colder water?**

a) The colder water will warm up (heat energy “flows” in to it). The warmer metal will cool down (heat energy “flows” out of it). b) The whole mixture will wind up at the SAMEtemperature. This is very, very important.

## How to find the final temperature of aluminum?

Find the final temperature when 10.0 grams of aluminum at 130.0 °C mixes with 200.0 grams of water at 25 °C. Assume no water is lost as water vapor. Solution . Again, you use q = mcΔT, except you assume qaluminum= qwaterand solve for T, which is the final temperature.

**What is the final temp of a chilled steel rod?**

A chilled steel rod (2.00 °C) is placed in the water. If the final temperature of the system is 21.5 °C, what is the mass of the steel bar? (specific heat of water = 4.184 J/g °C; specific heat of steel = 0.452 J/g °C)
