cual es el calor especifico de una sustancia cuya masa es de 7 gramos, si absorbe 180 calorias para pasar de 10 grados celsius a 85 grados celsius?

What is the specific heat of a substance whose mass is 7 grams, if it absorbs 180 calories to go from 10 degrees Celsius to 85 degrees Celsius

0.343cal/g°C

Explanation:

Given parameters:

Mass of substance  = 7g

Quantity of heat absorbed  = 180calories

Initial temperature  = 10°C

Final temperature  = 85°C

Unknown:

Specific heat of the substance  = ?

Solution:

To solve this problem, the specific heat of a substance is the amount of heat needed to raise the temperature of a unit mass of that substance by 1°C.

 Mathematically;

 C =  

C is the specific heat

Q is the amount of heat

m is the mass

T is the temperature

1 and 2 are the initial and final states

  Now, insert the parameters and solve;

           C  =   = 0.343cal/g°C

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
