Question

1. explain why sugar dissolves faster in hot tea than cold tea. (think about how the molecules are moving)

Explanation:

Temperature affects molecular motion. In hot tea, water molecules have higher kinetic energy (move faster) than in cold tea. Faster - moving water molecules collide more frequently and with greater force with sugar particles, breaking them apart (dissolving) more quickly.

Answer:

Sugar dissolves faster in hot tea than cold tea because temperature influences molecular motion. Hot tea has higher - temperature water, so water molecules move faster (have higher kinetic energy). These faster - moving water molecules collide with sugar particles more often and with more energy, which helps break the sugar particles apart (dissolve them) more rapidly than the slower - moving water molecules in cold tea.
