How many credits needed for master of arts degree?
It depends on the program of study. Typically, the masters degree can take 30 to 46 credits to complete with some upwards to well in the sixties.
How many gallons of water does it take to make a TV?
How much water is used to make a tv
Advantages and disadvantages of studying at university of technology or college?
The advantage of studying as a university or college that focuses on technology is that students can get a degree in a field that is in high demand. The disadvantage of this type of college is that it has a small amount of majors to choose from.
How many 120 degrees angles does it take to make a full turn?
A full turn is 360 degrees, so it would take three 120 degree turns.
Are you required to write a thesis for a Master of arts degree?
Whether a thesis is required for a particular Masters Degree is really up to the institution and/or the department. I did not have to do a thesis for my Masters, but did take a comprehensive. Viper1
If 705g of water is heated 889J how much will its temperature increase?
It take 4.2 Joules to raise 1 gram of water by 1 degree Celsius. Each gram of water is heated by 1.26 Joules, creating an increase in temperature of .3 degrees Celsius.
How many watts are required to raise 1 gallon of water 1 degree F?
1 gallon of water is 4540 cc and 1 degree F is 0.555 degrees C, so raising 4540 cc of water by 0.555 degree C would take 4540x0.555 calories, or 2520 calories. Multiply by 4.2 to convert to joules which gives 10590 joules. Therefore the energy required is 10590 joules which is the same as 10590 watt-seconds. That could be done by 100 watts in 105.9 seconds, or 1000 watts in 10.59 seconds.
Does it it take more energy to heat the water to 100 degrees celsius or boil it?
If by "boil" you mean have it all evaporate, that takes MUCH more energy. For example, to increase the temperature of one gram of water from 20 to 100 degrees Celsius, you need 4.2 joules/gram/degree times 80 degrees = about 336 joules; then, to evaporate all the water, you need an additional 2257 joules.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
15.37684 joules
How many calories does it take to heat 1 liter of water 1 degree?
It takes 1000 calories to heat 1 litre of water 1 degree C.
How many calories required to raise temperature of 1 liter of water 1 degree centigrade?
Well, let's see. Water at room temperature has a heat capacity of 4.18 J/g-C, and water also has a density of 1g/mL. If there's one litre of water, there's 1000 g of water. If the change in temperature is 1 C, and there are 1000 g of water, and specific heat capacity's 4.18... Q = mcT Q = (1000g)(4.18J/g-C)(1 C) Q = 4180 J So you need 4180 J of heat. *************************************** The definition of one calorie is as stated in the question. One calorie is equivalent to 4.18 Joules. Not sure where the maths went wrong but just so you know.
How many btu does it take at 212 F water?
Not sure exactly what you are asking but it takes 1 btu to raise the temprerature of 1 pound of water by 1 degree F. ( 4.2 joules to raise 1 lb by 1 degree Celsius ) so it depends on how much water we are talking about. there is also a transition to boiling where the water has reached 212 'F and has not yet begun to boil... it then takes an additional 970.3 btu's ( per lb ) for the water to achieve boiling, this is called the latent heat of vapourization .. hope this helps
How many joules does it take to heat up 15.1kg of glass to 15 degrees Celsius to 45 degrees Celsius?
3.8 x 10^5 Joules
How many joules of energy are necessary to heat sample of water with a mass of 46.0 grams from 0.0 to 100 C?
Assuming the water is liquid, the specific heat is about 4.186 joule/gram·°C, so to heat 46 grams of water would take about 192.556 joules/°C. The specific heat of ice is about 2.100 Joules/g·°C so heating 46 g of frozen water would take about 96.6 joules/°C. The specific heat of steam is about 2.020 Joules/g·°C so heating 46 g of water vapor would take about 92.2 joules/°C.
How much energy does it take to raise a volume of water by one celsius?
Well it depends on the volume of water. It takes one calorie per gram of water. Calorie is a unit of energy. It takes 4.18 Joule to raise one gram of water one degree. Joules are the scientific unit of energy. One gram of water has a volume of 1 cm3.
How do I convert the enthalpy of vaporization of water in joules per gram from kiloJoules per mole?
Lets say, for example the enthalpy is equal to 1200 joules/gram. You take 1200 joules/gram * (# of grams)/one mole [now you can cancel grams and it is now joules/mole.] Then convert the answer to kilojoules by dividing by 1000.
How many BTU's does it take to turn 32 degree water into 32 degree ice?
I assume you mean degrees Fahrenheit. First you must remove heat to make ice not add it. Next, the amount depends largely on the quantity (mass) of water being frozen. Water has a enthalpy of fusion of 333.55 KJ / Kg This means that for each kilogram of water you must remove 333.55 kilo-Joules to make it into ice. A conversion factor of 1 : 0.9478 between KJ and BTU gives us 316.14 BTU per Kilogram of water.
