What happens when the hot and cold water were mixed together?

When you heat up water, the water molecules start moving around faster and faster. So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top, mixing with the cold water along the way and creating purple water.

How did the heat lost by the hot water compare to the heat gained by the cold water?

The relationship between heat capacity and specific heat is C = m×sp_heat. Therefore, q = C×Δt and C = q ÷ Δt. In reality, the hot water loses heat to both the cold water and the calorimeter. In other words, heat gained by the cold water should equal that lost by the hot water.

What is the temperature of cold water and hot water?

Warm water is generally between 110 and 90 degrees Fahrenheit ( 43.3-32.2 Celsius). Cold water is between 80 and 60 degrees Fahrenheit (26.7-15 Celsius).

Which term is used to describe the measure of hotness and coldness of an object?

Temperature is the degree of hotness or coldness of an object. The temperature of an object, usually measured in degrees-Fahrenheit or degrees-Celsius, tells us how much heat, or energy, the object has.

Why heat capacity and density of water varies with temperature?

As the temperature increases, volumes of most of the liquids also increases and when the volume increases density decreases. Similarly, when temperature decreases, the volume of most liquids decreases which increases the density. Water has maximum volume at 4-degree Celsius and maximum density at 4-degree Celsius.

What is temperature of cold water?

70F(21C) Water feels quite cold to most people. Treat any water temperature below 70F (21C) with caution. 40F(4.4C) or lower Water is painfully cold.

Which of the two refers to the hotness or coldness of an object?

The degree of hotness or coldness of an object is called Temperature. The kinetic energy range in an object is measured by Temperature-the velocity of these particles increases as the temperature rises.

Why is density inversely proportional to temperature?

Density is inversely proportional to temperature because increasing temperature always causes the decompression of particles.

What is density how it varies with temperature?

As the temperature increases, volumes of most of the liquids also increases and when the volume increases density decreases. Similarly, when temperature decreases, the volume of most liquids decreases which increases the density.

What happens when hot water and cold water are mixed together?

Energy will move from the hot water molecules to the colder ones, until equilibrium is reached. Hot water has high temperature and cold water low temperature when they are mixed a equilibrium is attend .Equilibrium in the sence that the mixture will attin medium temperature You end up with warm water.

What is the difference between heat gained and lost by cold water?

In other words, heat gained by the cold water should equal that lost by the hot water. Any difference is due to heat gained by the calorimeter. This assumes no heat is lost to the surroundings from the calorimeter. Heat lost by hot water = heat gained by cold water + heat gained by calorimeter.

What happens to energy when two water molecules are mixed together?

Energy will move from the hot water molecules to the colder ones, until equilibrium is reached. In the end, the water will be at a middle temperature, the exact number being dependent on the two waters’ temperatures and volumes. The hot water loses energy to the cold water and the cold water gains energy from the hot water.

Does hot water evaporate faster than cold water in cold air?

Charles Evans ‘ answer is partially correct. Actually, hot water will cool much faster than cold water gains heat even if the temperature difference is the same. Hot water evaporates very fast in cold air, and evaporative cooling is a very efficient heat transfer mechanism.
