How might someones personality change after they had a drink?
they may become extremely nice or they may become very giggly
Does baking soda and vingar become a chemical change or physical change?
A chemical change, since there is carbon dioxide produced, a compound not previously present.
Is flash cameras flashing a chemical or physical change?
The flash of a camera is a physical change, not a chemical change. A physical change is a change in the form of a substance without changing its chemical composition. In the case of a camera flash, electrical energy is converted into light energy, which is a physical process that does not alter the chemical makeup of the components involved.
How do earthquakes change the atmosphere?
Earthquakes affect the atmosphere by creating amounts of dust which add to the air that we breathe. Earthquakes can also trigger volcanoes which will release tonnes of ashes and other particulates into the atmosphere. This can sometimes cause the blocking out of the sun (cooling effect), air pollution and an increased amount of carbon in the air (warming effect).
Is nitrogen change states a chemical or physical change?
Changing states of nitrogen, such as from a gas to a liquid, is a physical change because the chemical composition of nitrogen remains the same. It only involves a change in the arrangement of nitrogen molecules.
When liquid nitrogen boils at - 196 celsius is that chemical or physical changes?
The boiling of liquid nitrogen at -196 degrees Celsius is a physical change. This is because the change in state from liquid to gas does not involve a change in the chemical composition of the nitrogen molecules.
Is liquifying nitrogen a chemical change?
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
Does composition of the atmosphere change with elevation?
The atmosphere gos through many cycles and changes. The significant gases in our atmosphere have not changed substantially in the past several centuries. The primary gas is still Nitrogen, then Oxygen.
What are the consequences if nitrogen gas is absent from Earth's atmosphere?
If nitrogen gas were absent from Earth's atmosphere, it would disrupt the nitrogen cycle, affecting plant growth and nutrient cycling. This would lead to a decrease in food production, as nitrogen is an essential nutrient for plants. Additionally, the composition of the atmosphere would change, potentially impacting climate and ecosystem functioning.
How does the composition of gases change as you go higher into the atmosphere?
>>>>>...YOU CAN't breath
What would happen in nitrogen disappeared from atmosphere?
If nitrogen disappeared from the atmosphere, many organisms would die as they rely on nitrogen to build proteins and DNA. The loss of nitrogen would disrupt ecosystems, affecting plant growth and the animals that depend on them for food. Additionally, the composition of the atmosphere would change, potentially affecting climate and weather patterns.
Is liquid nitrogen that boils AT - 196 degrees Celsius chemical or physical?
Physical change, as it goes from nitrogen liquid to nitrogen gas ... No chemical change takes place.
Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
How does the composition of gases change as you travel up through earths atmosphere?
As the gases go higher in the atmosphere they start to compose or join together at some point which causes them to change since there is mixture of more than one gas, sometimes they form a different element when certain gases form
What does compotion of atmosphere mean?
The composition of the atmosphere refers to the various gases and particles that make up the Earth's atmosphere. It primarily consists of nitrogen (about 78%), oxygen (about 21%), and trace amounts of other gases such as argon, carbon dioxide, and water vapor. This mixture is crucial for supporting life, regulating the planet's climate, and protecting it from harmful solar radiation. Variations in atmospheric composition can influence weather patterns and climate change.
How did the earth's atmosphere change composition to become today's nitrogen and oxygen atmosphere?
The original atmosphere of Earth was lost when the solar wind of the early sun stripped away all the gas from around Earth. A secondary atmosphere was slowly released by volcanoes as gases were released from the molten rock. Most of this gas is carbon dioxide, but it is gradually dissolved in the oceans and precipitates out as carbonate rock instead of building up in the atmosphere.
