How many joules are needed to warm 675 grams of water (specific heat= 4.186 j/g degrees celsius) from 12 degrees celsius to 85 degrees celsius?

206,265.15 Joules are needed to warm 675 grams of water from 12 degrees Celsius to 85 degrees Celsius.

Explanation:

Between heat and temperature there is a direct proportionality relationship, where the constant of proportionality depends on the substance that constitutes the body. So, the equation that allows you to calculate heat exchanges is:

Q = c * m * ΔT

Where Q is the heat exchanged for a body of mass m, constituted by a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

Replacing:

Resolving you get:

Q=206,265.15 J

206,265.15 Joules are needed to warm 675 grams of water from 12 degrees Celsius to 85 degrees Celsius.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

the answer is either b or c
