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 happens when water vapour cools down below 100 degrees?
melts
Describe the motion of the particle of a solid as it cools from -250 degrees Celsius to -273.15 degrees Celsius?
They move at a slower pace until they stop and froze into place.
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...
When a substances cools it loses what energy to its surrounding?
When a substance cools, it loses thermal energy to its surrounding environment.
How many joules of heat are lost by 3580 kg of granite as its cools from 41.2 degreees Celsius to -12.9 degrees Celsius?
q = [ 0.803 J/( g degrees Celsius)] ( 2 multiplied by '10 to the power of 6' grams) ( 19 degree Celsius) q = 3.1 multiplied by '10 to the power of 7' Joules
How many joules of energy are released when 45.0 g of water cools from 18.0 oC to 7.0 oC?
energy = mass x specific heat x temperature change = 45 x 4.181 x 11 J = 2069.595 J
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
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
Does water that cools from 4 degrees celsius to 0 degrees celsius remain the same in density?
no. The density changes
Magma that cools quickly does it produce rocks that are fined grained?
Generally speaking, yes. Magma that cools quickly will produce small, "fine grained" crystals.Magma which cools slowly will generally produce rocks with larger, visible to the naked eye, crystals.This is because while magma is cooling, crystals are forming. Generally, crystal which have more time to grow will be larger. Therefore, generally, the slower magma cools, the bigger the crystals will be. The faster lava cools, the less time crystals have to grow and are thus smaller, "fine grained".
What is the heat change when 55.0g water cools from 60 degree celsius to 25.5?
q(joules) = mass * specific heat * change in temperatureq = (55.0 g H2O)(4.180 J/gC)(25.5o C - 60o C)= (- ) 7932 Joules=============heat change
