2 liters of water at 20 degrees, provided the mixing was not too vigorous and didn't last too long.
The final temperature of the water after mixing will be the average of the initial temperatures, which is (30 + 50) / 2 = 40 degrees Celsius.
The final temperature of the mixture will be between 5 and 20 degrees Celsius, closer to 5 degrees since a larger mass of water is at that temperature. To find the exact final temperature, you can use the principle of conservation of energy (Q lost = Q gained).

One liter of water weighs approximately 2.20462 pounds, regardless of the temperature.
It will freeze quicker ina colder temperature. What is the temperature ?
The final temperature of the mixture will be between 5 and 20 degrees Celsius, closer to 5 degrees since a larger mass of water is at that temperature. To find the exact final temperature, you can use the principle of conservation of energy (Q lost = Q gained).
No, as both the temperatures are the same, you will get only 2 cups, each 50 degrees. You have to heat the cup to get 100 degree.

The final temperature of the water after mixing will be the average of the initial temperatures, which is (30 + 50) / 2 = 40 degrees Celsius.
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.
99 g potassium chloride remain undissolved.
70 degree Celsius is qiute a high temperature. in this temperature, the water molecules starts escaping which results in the vapourisation of water.
25 degree celsius

Water has a very high specific heat capacity, which means you need to put a lot of energy into a given quantity of it to raise the temperature a given amount. The specific heat capacity of water is 4.187 kJ/kgK, which means you need to put in 4 kJ of energy to raise the temperature of one kg of water by 1 K (or 1C) Compare this to the specific heat capacity of air which is 1.0 kJ/kgK, or 25% of that of water. Therefore, you need to put in four times as much energy to heat up a given mass of water as compared to a given mass of air. One kilogram of air has a volume of about 29 cubic feet at 1 atmosphere, and a kilogram of water is a liter. It takes 4 times as much thermal energy to raise the temperature of that liter of water by a degree as it does to raise that 29 ft3 of air that same one degree. To do an additional comparison, you could picture a room that is 11' x 11' x 11' in volume. Elevating the temperature of the air in that room one degree will lift the temperature of that liter of water by the same one degree.
