The specific heat of water is 4.18 joules per gram Celsius. How much he does 225.0 g of water release when it cools from 85.5°C to 50.0°C

33387.75J

Explanation:

The amount of heat (Q) released from an heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Given that:

Q = ?

Mass of water = 225.0g

C = 4.18 joules per gram Celsius (4.18J/g°C)

Φ = (Final temperature - Initial temperature)

= 85.5°C - 50°C = 35.5°C

Then, Q = MCΦ

Q = 225.0g x 4.18J/g°C x 35.5°C

Q = 33387.75J

Thus, 33387.75 joules of heat is released during cooling.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

it means there are 3 atoms of oxygen
