Temperature Effects on Reaction Rate
Temperature Effects on Reaction Rate is how heating or cooling a substance changes how fast it reacts, like sugar dissolving faster in hot water than cold.
Think of it this way
Drop a sugar cube into a glass of cold water and another into a glass of hot water. The cube in the hot glass dissolves much faster. Heat makes the water molecules move quicker, so they bump into the sugar more often and break it apart sooner. Cold slows everything down.
Explaining temperature effects on reaction rate by grade level
Think about dropping sugar into a cold glass of water and a hot cup of water. In the cold water, the sugar sits there a long time. In the hot water, it disappears much faster. Heat makes things mix and change quicker. Cold slows them down. The hotter something gets, the faster changes happen.
