Question

What mass of water is required to absorb 4.7 x 10 to the 5th power J of energy from a car engine while the temperature increases from 298K to 355 K

Answer 1

The mass of water required to absorb 4.7 x 10^5 J of energy from a car engine while the temperature increases from 298K to 355K is approximately 21.5 kilograms.

Step-by-step explanation:

To calculate the mass of water required to absorb 4.7 x 10^5 J of energy, we can use the equation:

Q = mcΔT

Since we know the initial and final temperature (298 K and 355 K respectively), we can rearrange the equation to solve for mass:

m = Q / (cΔT)

Plugging in the values, we get:

m = (4.7 x 10^5 J) / (4184 J/kgK * (355 K - 298 K))

Calculating this, we find that the mass of water required is approximately 21.5 kilograms.
