What is alcohol fermentation?
a measure of the force of gravity on an object
What is weight?
a characteristic of a substance that may be observed without changing the substance into something else
What is a physical property?
Identify the phase change that occurs and the name of this process at the arrow labelled "6".
the ratio of output force to input force
What is mechanical advantage?
A and B, and C and D in the cladogram provided are organisms more closely related to each other than to other organisms in the ingroup. What are these taxa called?
What are sister taxa?
a unique temperature and pressure at which three phases of a substance can exist together
What is the triple point?
a marshmallow is cut in half and then roasted over a campfire
What is a physical change (cut in half) and a chemical change (roasted over a campfire)?
Identify on the provided phase diagram, the number identifying where this substance can exist in all three phases simultaneously.
What is the red point labelled "11"?
using a force to move an object a distance, with both the force and the motion of the object in the same direction
What is work?
this is the broadest group in the classification system developed by Carl Linnaeus
What is the domain?
this is the temperature and pressure at which a substance's liquid and gas phases no longer exist as distinct phases
What is the critical point?
a change in physical properties is evidence of this type of change
What is a chemical change?
The name of the process occurring where the red arrow labelled "5" is located on the phase diagram.
What is sublimation?
1/2 mv2 is the formula for calculating this form of energy
What is kinetic energy?
the potential energy of a 50 kg object that is 20 meters above the ground
PE = mgh, where g = 9.8 m/s^2
What is 9800 joules?
PE = (50 kg)(9.8m/s^2)(20 m)
