Sustainability and DOPHHAE
what is Carbon footprint?
The total amount of greenhouse gases emitted into the atmosphere as a result of human activities.
How does Concentration effect rate of Reaction?
The higher the concentration of reactants, the faster the rate of a reaction will be.
Potential energy is stored but Kinetic energy is?
Energy of motion
What is a crest?
The highest point on a wave.
Sound mechanical but Light is?
Light is electromagnetic.
What are Emissions?
The release of pollutants or gases, especially greenhouse gases like carbon dioxide.
How does Temperature effect Rate of Reaction?
If more molecules hit each other with enough energy to react, then the rate of the reaction increases.
Potential and Kinetic Energy are both what type of Energy?
They are both mechanical Energy.
What is a trough?
The lowest point on a wave.
does sound need a medium or does light need a medium?
sound needs a medium.
What is a Sustainable development?
Development that meets the needs of the present without compromising the ability of future generations.
How does surface area effect Rate of Reaction?
It boosts the chance of a collision in particles which increases the rate of reaction.
What does there need to be in order for there to be more Kinetic Energy?
There needs to be more mass.
What is wavelength?
It is the distance between corresponding points of two consecutive waves.
Light moves through a vacuum.
What are the types of Renewable energy?
Sunlight, wind, rain, tides, and geothermal heat.
What are Catalysts?
Catalyst is a substance which increases the rate of a chemical reaction but it is not used up (remains chemically unchanged at the end).
Does a car going down the highway have Kinetic Energy?
A car going down the highway has Kinetic Energy.
What is amplitude?
Amplitude is the measurement of the amount of energy transferred in a wave.
Does light or sound involve the movement of molecules?
Sound involves the movement of molecules.
What are the terms of DOPHHAE?
Decrease in Natural Resources, Overexploitation, Pollution, Habitat destruction, Habitat fragmentation Acid rain, Eutrophication.
How do Inhibitors effect Rate of Change?
Inhibitors decrease the rate of a reaction by reducing the activity of the reactants or catalysts.
An object at a height has what type of potential?
It has gravitational potential.
What is an Expansion?
It is where particles are spread apart on a wave.
Light is a form of mechanical energy but also is a form of what type of energy?
light is a form of radiant energy.
