Basic Concepts and Units in Measurement Homework 2B

Physics6 CardsCreated 5 months ago

This deck covers fundamental concepts and units used in measurement, including conversion factors, surface area calculations, temperature descriptions, and definitions of density and concentration.

The fact that 1 liter = 1.057 quarts can be expressed as the following conversion factor.

1.057 quarts/1 liter because multiplying it by any number of liters would convert the number from liters to quarts by causing the units of liters to cancel without changing number because the factor is equal to 1.

You are given two pieces of​ information: (1) the volume of a lake in cubic feet and​ (2) the average depth of the lake in feet. You are asked to find the surface area of the lake in square feet. What should you​ do?
Divide the volume by the​ depth, because this will cancel the depth in the volume and give feet square in the numerator which are the units for surfac...
Which statement best describes a temperature of 110°C
Hot enough to boil​ water, since 110°C is above the boiling point of water.
What do we mean by​ density?
Density is used to describe compactness or crowding.
What do we mean by​ concentration?
Concentration refers to the amount of a substance present in a certain volume of solution or space. It indicates how much solute is dissolved in a sol...
Describe common units of​ density, concentration, and blood alcohol content.
Common units for density are g/cm3​, people/mi2​, and GB/in2. Common units for concentration are ppm and ml/mg. Common units for blood alcohol content...
