Fossil fuels
What makes up fossil fuels?
Decomposing plants and animals
The viscous force the relative motion between the adjacent layers of a fluid in motion.
Which one of the flowing fits best in the sentence?
a) opposes
b) never affects
c) facilitates
d) may effect under certain conditions
Answer: a
Explanation: Viscosity is the internal friction of a fluid in motion. It is the property by the virtue of which the relative motion between two adjacent fluid layers is opposed.
What makes up molecular chlorine?
Cl2
What does exothermic do?
Gives off heat
What is element 22?
Titanium
Name at least one example of a fossil fuel.
Coal, oil and natural gas
The viscosity of a fluid in motion is 1 Poise. What will be it’s viscosity (in Poise) when the fluid is at rest?
a) 0
b) 0.5
c) 1
d) 2
Answer: c
Explanation: Viscosity is the property of a fluid and is constant for a given fluid under given conditions, irrespective of the fact whether the fluid is at rest or in motion.
What makes up Chloromethane?
CH3Cl
What does endothermic do?
Absorbs heat
What is element 1?
Hydrogen
Where are fossil fuels found?
Underground trapped in deposits surrounded by layers of rock.
What is viscosity?
A liquid resistance to flow
What makes up molecular nitrogen?
N2
What are the 5 phase changes?
Sublimation, deposition, condensation, evaporation, freezing, and melting
What is in the alkali metal family?
alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What are the two biggest coal mines in the US?
The two largest coal mines in the United States are the North Antelope Rochelle and Black Thunder mines in Wyoming.
What causes viscosity?
Viscosity is a measure of the resistance of a fluid towards being deformed when under shear stress. Hence, it is also known as shear viscosity. It is caused by the attractive forces between molecules in close contact, and the friction between molecular chains.
What makes up nitrosoxide?
N2O
What phase change is boiling?
As a liquid boils, it is undergoing the liquid to gas phase change. In order to do this, the intermolecular forces present in the liquid state must be overcome.
What number is chlorine?
17
What is the Stanford team trying to reduce?
trying to remove carbon dioxide from the atmosphere and store it underground—a process called carbon capture and sequestration.
What are the types of viscosity?
Viscosity is the measure of a liquid's resistance to flow. There are two types of viscosity: Dynamic viscosity and Kinematic viscosity.
What makes up Methane?
CH4
What makes up condensation?
Liquid to gas
What is element 3?
Lithium
