How your hands will feel when you place them in the container of room temperature water?
Body temperature is regulated by an intricate system called homeostasis. If the external (outside) temperature is hotter or colder than our body then various things come into play to maintain our body heat. If you put your hand into room temperature water (room temperature is generally accepted to be 20 degrees C) then it will feel cold, because body temp is about 37 degrees C. The water will absorb heat energy from your hand, making it feel cold, until the temperature of the water and the temperature of your hand are the same. Or until you decide that shoving your hand in cool water is pointless...
If you put your hand into water that is at 37 degrees C then you won't notice any temperature difference. It just feels wet. It's really weird, try it!
What else can I help you with?
How can you boil water at a temperature lower than 100 celsiuse?
Place the container of water in a vacuum & it should start to boil at room temperature.
Which container contains water with lower initial temperature?
You think probable to a Dewar container.
What is the temperature of tap water placed outside in sun for 6 hours?
That would depend on many factors, such as the material the container is made of, the color of the container, how much water is in the container, and the starting temperature of the water. You really need to measure the temperature after six hours with a thermometer.
What causes the difference on hotness or coldness of the water inside the container?
The difference in hotness or coldness of water inside a container is primarily caused by the temperature of the water and the surrounding environment. Heat transfer occurs through conduction, convection, and radiation, affecting the water's temperature. Additionally, factors such as the material of the container, the initial temperature of the water, and the duration of exposure to heat or cold sources play a significant role in determining the final temperature.
When the steam in the container changes to liquid water at room temperature will the container still be full?
When the steam in the container condenses into liquid water at room temperature, the container will not necessarily remain full. The volume of steam is much larger than that of the liquid water it converts into, so the container will likely have some empty space left. Additionally, if the container was initially sealed, it may also experience a slight decrease in pressure, which can further affect the amount of liquid present.
How can you boil water at a temperature lower than 100 celsiuse?
Place the container of water in a vacuum & it should start to boil at room temperature.
How can I make a simple calorimeter?
To make a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the container with water on the heat source and measure the initial temperature. Apply heat to the water and record the temperature change. By measuring the amount of heat applied and the temperature change, you can calculate the heat capacity of the calorimeter.
When you put your hands in the water at he room temperature why do you not feel cold?
If the water is room temperature, meaning the same temperature as the air, then you wouldn't feel a change in temperature. On the other hand, If there was a breeze or the air was otherwise in motion, it might increase evaporation of skin moisture and have a cooling effect. In that situation, putting your hands into the water might make them feel warmer.
Which container contains water with lower initial temperature?
You think probable to a Dewar container.
If equal amounts of heat are added to two containers of water and the resultant temperature change of the water in one container is twice that of the wa ter in the other container then what can you sa?
The specific heat capacity of the water in the container with the larger temperature change is lower than that of the water in the other container. This means that the water with the larger temperature change requires less energy to heat up.
What is the temperature of tap water placed outside in sun for 6 hours?
That would depend on many factors, such as the material the container is made of, the color of the container, how much water is in the container, and the starting temperature of the water. You really need to measure the temperature after six hours with a thermometer.
How can I build a simple calorimeter?
To build a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the heat source under the container, measure the initial temperature of the water, and then record the temperature change as the heat source warms the water. This will help you calculate the amount of heat energy released by the heat source.
How might you keep the water warm longer after you remove it from the sunlight?
You can insulate the container with a towel or place it in a thermos to keep the water warm longer after removing it from sunlight. Additionally, using a lid or covering the container will help retain the heat. Finally, placing the container in a warm spot indoors can also help maintain the water temperature.

How fast will a surface of water 20ft x 40ft x 20inches freeze?
It depends upon the temperature of the water, the temperature of the container and the temperature of the atmosphere.
What is the recommended temperature range for tepid water when used for washing hands?
The recommended temperature range for tepid water when used for washing hands is between 60F and 100F.
How can I make a styrofoam calorimeter?
To make a styrofoam calorimeter, you will need a styrofoam cup, a lid for the cup, a thermometer, and a stirrer. Cut a hole in the lid to insert the thermometer. Fill the cup with a known volume of water and record its initial temperature. Place the cup in a larger container filled with water and heat or cool the water to a desired temperature. Place the lid on the cup and stir the water to ensure even temperature distribution. Record the final temperature of the water to calculate the heat exchange.
