Question

Explain how does placing of tea in closed vessel help in understanding system and surrounding?

Answer 1

System and surrounding

• Reactants and products are collectively referred to as the system for chemical reactions.
• Type of system: open system and closed system.
• The area around the reaction, including the room and the reaction flask, is called the surroundings.
• Energy is moved from the system to its surroundings during a reaction.

Tea in a closed vessel

• Compared to the room where it is kept, the tea is very energetic.
• As time goes on, the tea's heat will spread throughout the room.
• The tea will grow cold.
• Here, the room act as a surrounding for tea.
• Here, tea is an example of a closed system because when it is placed in a closed vessel, only energy is exchanged with the surroundings.
• This occurs as a result of the energy (heat) in the tea spreading to the surroundings.
• There is no more heat that can be diffused once the tea has cooled.
