How much heat is lost by water as 0.250kg cools from 35 degrees Celsius to 20 degrees Celsius?

0.450 kg = 450 grams
q = mass * specific heat * change in temp.
q = (450 grams)(4.180 J/gC)(20 C - 35C)
= - 2.8 X 10^4 Joules of heat lost

What is the density of water at 20 degrees Celsius-?
What is the density of water at 37 degrees Celsius?
What physical state of water -24 degrees Celsius?
Water freezes solid at 0 degrees Celsius, so it will still be solid at -24 degrees Celsius.
What is th difference between celsius and fahrenheit?
The difference between Celsius and Fahrenheit is that in Celsius, the freezing point of water is 0 degrees Celsius and the boiling point is 100 degrees Celsius. In Fahrenheit, the freezing point of water is 32 degrees Fahrenheit and the boiling point of water is 212 degrees Fahrenheit.
Physical state of water at 25degree celsius?
At sea level (1 atmosphere), water is a liquid at 25 degrees Celsius. The freezing point of water at sea level is zero degrees Celsius, and the boiling point is 100 degrees Celsius.
How long does it take to freeze 4 cups of water at 17 degrees Celsius?
You can't freeze water at 17 degrees Celsius. The freezing point of water is 0 degrees Celsius or 32 degrees Fahrenheit.
Does water that cools from 4 degrees celsius to 0 degrees celsius remain the same in density?
no. The density changes
Is 25 degree Celsius considered cool?
calulate the amount of heat released when 25 gram of water at 25 degrees Celsius cools to 0.0 degrees celsius
When a liquid cools to be a solid?
It is called the freezing point or crystallization point. In water it is 0 degrees Celsius
What happens to water at 4 degrees Celsius?
at -4 degrees celsius if the water is a solid state of matter,it will turn into a liquid
What happens to the of water vapor when the temperature of the gas cools to 100 degrees Celsius?
at standard pressure, the vapor condenses to liquid water at 100 C
Why does water expands at 4 degree celsius?
Water has curious thermal properties. It contracts (gets denser) as it cools down just like other materials. However, at 4 degrees Celsius, it reaches the maximum density of 1 and then starts expanding if it is further cooled. Ice formed at zero degree Celsius is actually less dense than water and floats on it.
What happens to the molecules of water vapor when the temperature of the gas cools 100 degrees Celsius?
at standard pressure, the vapor condenses to liquid water at 100 C
What happens to the molecules of water vapor when the temperature of gas cools to 100 degrees Celsius?
at standard pressure, the vapor condenses to liquid water at 100 C
What is the boiling point(in degrees Celsius) of water?
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
What is the boiling point of water in degrees Celsius on a thermometer?
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
What is the degrees for boiling water in Celsius?
100 degrees Celsius
What is the boiling point ( in degrees celsius ) of water?
It is 100 degrees Celsius that water boils at.
