Lower Sec Science · Secondary 1 · Hard · Solubility
A beaker of water at 20 °C dissolves 5 g of a salt before becoming saturated. The same volume of water at 60 °C dissolves 12 g of the same salt before becoming saturated. Which statement best explains this observation using the particle model?
- Heating increases the space between water particles so more solute can fit.
- Heating increases the size of water and solute particles.
- Heating increases the number of water particles in the beaker.
- Heating increases the mass of each solute particle.
