Lab Equipment
The piece of equipment used to measure the mass of an object or substance
What is a scale?
Density = mass / volume
The most dense state of matter
What is solid?
State the Ideal Gas Law
What is pv = nrt?
The definition of climate
What is average weather over a period of 30 years?
The piece of equipment used to hold liquids
What is a beaker or Erlenmeyer flask?
The density of an object with a mass of 5.28 g and a volume of 2 mL.
What is 2.64 g/mL?
The state of matter with the most kinetic energy
What is gas?
The units used to measure pressure
What is atmospheres (atm)?
Two greenhouse gases present in our atmosphere
What is carbon dioxide, methane, or nitrous oxide?
The piece of equipment used to precisely measure amounts of liquids
What is a graduated cylinder?
The order these liquids would be in a density column: Water (1.00 g/mL), Oil (0.79 g/mL), soap (0.50 g/mL), your tears (1.02 g/mL)
From bottom to top: tears, water, oil, soap?
The relationship between pressure and volume
What is inverse? (When one increases, the other decreases)
The units used to measure the amount of the gas
What is moles?
The definition of the greenhouse effect
What is greenhouse gases in the atmosphere absorb heat from the sun?
The piece of equipment used to pick up or hold objects
What is tongs?
The density of this object: It has a mass of 107 g. When placed into a graduated cylinder full of 10 mL of water, it causes the water to rise to 15 mL.
What is 21.4 g/mL?
The relationship between pressure and temperature
What is linear? (When one increases, so does the other)
The temperature in a 25.0 L tank containing 2.10 moles of N2 gas at a pressure of 1.25 atm
What is 181.25 K?
Two impacts of climate change
What is global warming, increased rainfall, more severe winters, more frequent droughts and forest fires, more frequent hurricanes, etc.
The piece of equipment used to light bunsen burners
What is a striker?
The density of this object: it has a mass of 184.32 g. It's a block measuring 3 cm by 4 cm by 6 cm.
What is 2.56 g/mL?
The reason popcorn pops
What is the increase in temperature causes an increase in pressure in the kernel, and over 9.2 atm the pressure is so strong the kernel rips open?
The pressure in a 212 L tank containing 2.3 moles of argon gas at 25 degrees Celsius.
What is 0.27 atm?
Two solutions to climate change
What is planting more trees, reducing deforestation, reducing the production of greenhouse gases, and/or engineering products to reduce greenhouse gases
