Answer:
limestone < slime < hot coffee < helium balloons
Step-by-step explanation:
The order is based on the average kinetic energy of the particles in each object. The order increases as the temperature of the object increases, causing the particles to move faster and have more kinetic energy.
1. Limestone: Solid-state mineral with relatively low temperature and slow-moving particles, lowest kinetic energy among the objects listed.
2. Slime: A non-Newtonian fluid that can be considered as a soft solid, its particles have more kinetic energy than solid limestone, but less than a liquid like hot coffee.
3. Hot Coffee: A liquid with a higher temperature than the other objects, particles have more kinetic energy compared to solid or non-Newtonian fluid.
4. Helium Balloons: Gas with a higher temperature than the other objects, particles have the highest kinetic energy among the objects listed, resulting in the balloon expanding and rising.
