delta T x specific heat x mass Delta T = change in temperature specific heat of water = 4.1813 J/gC Mass= 45.0g 48C-14C=34C 34 C x 4.1813 J/gC=142.1462 J/g 142.1462 J/g x 45g = 6397.389 J restricting us to three significant digits = 6.40 x 10^3 J

∙ 12y agoq(joules) = mass*specific heat*change in temp.
A few conversions for my benefit.
14.00 kg = 14000 grams
q = (14000 g)(4.180 J/gC)(46.5 C - 24.8 C)
= 1269884 Joules (1 kj/1000 J)
= 1270 kilojoules

Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
These are not temperature numbers but specific heat numbers. They mean that it takes 4.184 Joules and 0.387 Joules respectively to raise water and copper of one gram by one degree celsius. So, as you can see, it takes a lot more heat to raise the temperature of water than it does of copper. Water has a very high specific heat.
How much heat in joules is needed to raise the temperature of 4.0 L of water from 0 degrees Celsius to 70.0 degrees Celsius?
It takes 4.186 Joules to heat one gram of water by 1-degree Celsius. 4.186 * 4000 = 16,744 Joules to heat 4 kilos of water by 1-degree. 16,744 * 70 = 1,172,080 Joules. The above assumes that one litre of water weighs exactly 1 Kilogram.
What is the metric unit of temperature?
We use Fahrenheit. In Europe they use Celsius degrees. The Kelvin is the metric unit.
What is specific temperature?
Specific temperature is an amount of heat per unit mass required to raise the temperature by one degree Celsius.
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?

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 joules does it take to warm water by 1 degree?
It takes 4186 joules to raise the temperature of 1 kilogram of water by 1 degree Celsius. The mass does make a difference.
What is the amount of energy needed to raise the temperature of 1 gram of water 1 degree celsius?
The amount of heat necessary to raise 1 gram of a substance by 1 degree Celsius is known as?
How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================
A particular sample of iron requires 562 Joules to raise its temperature from 25 degreee Celsius to 50 degrees Celsius. What must be the mass of the sample of iron?
The change in temperature is 25 degrees Celsius, meaning it takes 22.48 joules per degree of change. The specific heat of iron is 0.449 J/g degree Celsius. This means that the mass of iron must be 50.07 grams
How much energy is required to raise 21kg of water by 2 degrees Celsius?
21 Kg = 2100 grams to rise the temperature of this amount of water by 2 degrees Celsius you need 2*2100 = 4200 calories or 17572.8 Joules.
How much energy is required to raise the temperature of 1 g of water 1 degree Celsius?
Energy required to raise 1 gramme of water by 1 degree C = 1 calorie also, 1 calorie = 4.186 Joules
How many calories are required to raise the temperature of 150 g sample of gold from 25 Celsius to 175 Celsius?
I will use this formula, the convert. q( in Joules ) = mass * specific heat Au * change in temp. q = nCT q = (150 grams)(0.129 J/gC)(175 C - 25 C) = 2902.5 Joules Now, 1 calorie = 4.184 Joules 2902.5 Joules (1 calorie/4.184 Joules) 694 calories required
What is the quantity of heat in joules needed to raise the temperature of 40.0g of Al from 25 degrees Celsius to 50 degrees Celsius?
E = mass x specific heat x Δ°T Δ°T = new temperature - original temperature where Δ°T is equal to temperature change (Celsius in this case). The specific heat of Al is 0.900 J/g°C. Before we proceed to find the quantity of heat in joules, we must first find the temperature change. To calculate the temperature change, we must subtract the original temperature from the new temperature. Δ°T = 50°C - 25°C = 25°C In order to find the quantity of heat (joules), we must multiply mass, specific heat, and the temperature change (calculated above). E = 40.0g x 0.900 J/g°C x 25°C = 900 Joules or 9.0 x 102 Joules
