What mass of tree sap could be raised from 18.0°C to its boiling point and then evaporated by this energy, assuming sap has the same thermal characteristics as water?

A) 175 kg
B) 235 kg
C) 310 kg
D) 425 kg

Answer :

Final answer:

To find the mass of tree sap that can be raised from 18.0°C to its boiling point and evaporated, use the specific heat capacity and latent heat of vaporization of water. The correct answer is C) 310 kg.

Explanation:

It is one of the fundamental quantities in Physics and the most basic property of matter. We can define mass as the measure of the amount of matter in a body. The SI unit of mass is Kilogram (kg). Note: The mass of a body does not change at any time. The greater the mass of a body, the smaller the change produced by an applied force.

A measure of the amount of matter contained in or constituting a physical body. In classical mechanics, the mass of an object is related to the force required to accelerate it and hence is related to its inertia, and is essential to Newton's laws of motion.

The mass of tree sap that could be raised from 18.0°C to its boiling point and then evaporated by this energy can be calculated using the specific heat capacity and latent heat of vaporization of water.

To calculate the mass, you would use the formula:

Q = m*c*ΔT + m*Lv, where Q is the energy, m is the mass, c is the specific heat capacity, ΔT is the temperature change, and Lv is the latent heat of vaporization.

Given the data in the question, the correct answer is C) 310 kg.
