Question

2. How many grams of water can be warmed from 25.0°C to 37.0°C by the addition of 8,064 calories?

Answer 1

672 g

Step-by-step explanation:

We can calculate the mass of water that can be warmed from 25.0°C to 37.0°C by the addition of 8,064 calories using the following expression.

`Q = c * m * \Delta T`

where,

c: specific heat of the water

m: mass

ΔT: change in the temperature

`m = (Q)/(c * \Delta T ) = (8,064cal)/((1cal/g. \° C) * (37.0 \° C - 25.0 \° C) ) = 672 g`

The mass of water that can be warmed under these conditions is 672 grams.
