Question

Among the following temperatures, the motion of water particles will be fastest at ____.

• A. ${50}^0$C
• B. $0^0$C
• C. ${100}^0$C
• D. ${10}^0$C

Answer 1

The correct option is C ${100}^0$C

When anything is heated, at the microscopic level, particles start moving faster and their temperature rises. This means that they have a higher kinetic energy. So, higher the temperature, higher the kinetic energy and the motion of the particles. This makes ${100}^0$C the temperature at which they have the fastest particles.
