Climate Change + Earth
This greenhouse gas is released when fossil fuels are burned and helps trap heat in Earth’s atmosphere.
What is carbon dioxide?
The positively charged particle in the nucleus.
What is a proton?
What are the electrons in the outermost energy level?
What are valence electrons?
Objects float if their density is ____ than water.
The force between two charged objects.
What is the electrostatic force?
Coastal cities have milder temperatures because water has a high ______.
What is specific heat?
Neutrons are found in this part of the atom.
What is the nucleus?
Water molecules sticking to each other is called _____.
What is cohesion?
Density depends on these two variables.
What are mass and volume?
Objects with the same charge will do this.
What is repel?
A relationship where two variables change together but one does not necessarily cause the other.
What is correlation?
An atom with more electrons than protons has this charge.
What is negative?
Water is polar because electrons are shared _____.
What is unequally?
True or false: Objects that weight the same always have the same density.
What is false?
Coulomb’s Law describes the force between these.
What are charged objects?
Darker land absorbs more sunlight after ice melts, causing warming due to lower _____.
What is albedo?
Which subatomic particle is NOT counted when determining charge?
What is the neutron?
Draw the electron shell model for a neutral atom of beryllium on the board.
4 protons, 2 electrons in each shell.
Predict whether an object with density 1.2 kg/L will float or sink. Remember water's density is 1.0 kg/L. Explain.
What is sink because density of the object is greater than the density of water?
As distance between charged objects decreases, electrostatic force does this.
Why does a decrease in albedo accelerate climate warming?
What is more solar energy is absorbed?
Which particle must be transferred for an atom to become charged?
What is electron?
Why do atoms bond with other atoms?
What is to complete their outermost energy shell and become stable?
An object has a mass of 6 kg and a volume of 3 L. Its density is:
Remember D=m/v
What is 2 kg/L?
The electrostatic force calculated using Coulomb’s Law is measured in these units.
What is Newtons (N)?
