Answer:
The substance with the highest heat gives heat to the lowest temperature, equating both temperatures,
In this situation there is talk of giving up heat but not matter, it is here that the law of conservation of energy comes into play.
Explanation:
The law of conservation of energy talks about that energy is transformed and never lost between two substances or two bodies that interact with each other, these interactions can be heat exchanges, as in this example.
Answer: Option (B) is the correct answer.
Explanation:
Natural gas is defined as the gas which is formed naturally beneath the surface of Earth that mostly contains methane and small amounts of ethane, propane etc.
Since, natural gas upon burning produces water and carbon dioxide resulting in the release of a clean gas as compared to other fuels. Carbon dioxide produced upon burning of natural gas is 50-60% lesser in amount as compared to release of carbon dioxide upon burning of coal.
Therefore, we can conclude that burning coal produces more carbon dioxide than burning natural gas.
When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation. Precipitation occurs in a variety of forms; hail, rain, freezing rain, sleet or snow.
When the temperature is too hot for snow it'll rain and if the tempature is too cold it will freeze the rain and that's how you get snow or hail.
Hope this helped :)
Have a great day
Answer:
a.substitution
Explanation:
because one of the hydrogen atoms from the methane is replaced with a bromine atom.Alkanes undergo a substitution reaction with halogens in the presence of light. For example, in ultraviolet light , methane reacts with halogen molecules such as chlorine and bromine. This is a substitution reaction because one of the hydrogen atoms from the methane is replaced by a bromine atom.
Answer:
People, especially kids, tend to think that when water evaporates it just disappears, or turns into the air. But we know based on the law of conservation of mass that any time water changes state it keeps the same mass!
Similarly, when water vapor turns to water droplets, when it goes from its gas to its liquid state, it still has the same mass. It's just in a different phase. This is a perfect example of conservation in mass!
