What mass of water will give up 240 calories when its temperature drops from 80 to 68?
if this is for basic physics, then the specific heat capacity of water is 1000cal/(Kg * degree centigrade). in other words, 1000 calories are released for every kilogram of water that cools 1 degree, or 1 calorie is released for every gram of water that cools 1 degree. so if 1 calorie released = 1 g...
What else can I help you with?
What is temperature of water drops it continues to give off thermal energy until it freeze example of?
An example of water continuously giving off thermal energy until it freezes is when you leave a glass of water in a freezer. As the water's temperature decreases, it releases thermal energy to the surrounding air until it reaches the freezing point, forming ice crystals.
How can you say that water vapour are present in air give an activity to explain it?
One way to show that water vapor is present in the air is to cool the air. If the air temperature drops below its dew point, water vapor in the air will condense into tiny droplets, forming visible fog or mist. This process demonstrates that water vapor is a component of the air.
How many btus does it take to heat up one gallon of water?
That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
What piece of laboratory equipment would be most appropriate to measure hot water of 300 ml in the bath tub as it heats?
A thermometer would be the most appropriate laboratory equipment to measure the temperature of the hot water in the bathtub as it heats. It can give you an accurate reading of the water temperature as it warms up.
Thermometers need numbers on a ----- to give a temperature reading?
Thermometers need numbers on a scale to give a temperature reading.
Can you give some mathematical problems related to heat of fusion?
This is the formula for finding calories: calories= (Tf-Ti)mass Or, in words, you subtract the final temperature (the temperature of the fused waters) by its initial temperature (the hot/ cold water's original temperature). You then multiply this answer by the mass of the water before you mix them together. Your hot and cold water should both have the same mass, but not the same temperature.
Water must contain calories not Calories which is 1000 calories otherwise Einstein is wrong about matter and energy being the same So how many calories in water?
There aren't any calories in pure water. Water doesn't give you energy, so therefore it doesn't have any calories.
Why does drinking milk supply your body with energy but water does not?
Milk contains calories which give you energy. Water doesn't contain calories.
What properties give water such a high specific temperature?
The polar properties of water give it such a high specific temperature.
How can you give a poisonous spider water to drink?
carefully spray tiny drops of water on its web
Can evaporation take place without the increase in temperature Give example.?
Yes. When you cool by sweating - it drops.
What is temperature of water drops it continues to give off thermal energy until it freeze example of?
An example of water continuously giving off thermal energy until it freezes is when you leave a glass of water in a freezer. As the water's temperature decreases, it releases thermal energy to the surrounding air until it reaches the freezing point, forming ice crystals.
What is the teampature of the water?
The temperature of water is so variable, that it is impossible to give an answer.
What is thre function of a bomb calorimeter?
it burns food and that heats water to give a reading in calories
Should you give a dehydrated person cold water?
no, sips of room temperature water.
Is there special water for guinea pigs?
No there is not special water for guinea pigs. Although there are vitamin drops you can put in the water. I currently have a guinea pig and I give her tap water with nothing added.
What are some foods with no calories?
Celery and water is all i know but there are food that give you "negative calories" which is basically what it stands for you will lose calories when eating stuff like Asparagus,Apple,Beet,Cranberries, broccoli and etc.
