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

How many calories are required to increase the temperature of a 27.3 g sample of copper from 36.2 degrees Celsius to 74.4 degrees Celsius?
I will work in Joules, then convert to calories.q(Joules) = mass * specific heat * change in temperature Cq = (27.3 g Cu)(0.385 J/gC)(74.4o C - 36.2o C)= 402 Joules (1 calorie/4.184 Joules)= 96.1 calories===========
When the temperature of a sample of water is negative 5 degrees Celsius the water is?
Frozen (23F)
A scientist measures the temperature of a sample of hydrochloric acid to be 85 celsius what is its temperature in kelvin?
85 + 273 = 358 K.
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
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
If a 1.0-g sample of steam at 100 degrees Celsius loses 560 calories of heat what would the resulting temperature of the steam sample be?
80

38 cal
how many calories are required to increase the temperature of a 27.3 g copper sample from 36.2 degrees C to 74.4 degrees C?
80 calories per gram
Why would water in a 100cm3 and water a 10cm3 cylinder measure the same temperature?
Because they are the same temperature. There are more calories of heat in a 100-ml sample of water that's at a certain temperature than there are in a 10-ml sample that's the same temperature...but 20-degree-Celsius water is 20-degree-Celsius water whether you have a thimbleful, a glassful or a swimming pool full.

How much ice water will it take to cool the sample to 20 degrees celsius?
That would depend on the mass of the sample, its temperature, and what the sample is made of.

The temperature of the water is 100 degrees celsius.
) The temperature of a sample of water changes from 10 and degC to 20 and degC when the water absorbs 100 calories of heat. What is the mass of the sample?
one calorie of heat is able to raise one gram of water one degree Celsius so 400 calories could raise 1g of water 400 degrees, so it would raise the 80g by(400/80) 5 degrees Celsius plus the initial temp of 10 degrees, the 80g of water would have a final temp of 15 degrees Celsius
