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

it's c. elements are placed in rows based on how may valencies electrons have.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
