Question

a wooden floor put down in cool weather. As theweather became warmer, the floor started to buckle, rising up in themiddle of the floor. The floor was fixed by trimming the edges of thefloor so that there was a space between the flooring and the wall.Choose the response that best explains why this helped to make thefloor flat again.A. The particles in the floor decrease in thermal energy in warmweather, decreasing the kinetic energy of its particles and making itexpand. Trimming it gave it room to expand.B. The particles in the floor increase in thermal energy in warmweather, increasing the kinetic energy of its particles and making itexpand. Trimming it gave it room to expand.C. The particles in the floor decrease in thermal energy in warmweather, decreasing the kinetic energy of its particles and making itcontract. Trimming it gave it room to contract.D. The particles in the floor increase in thermal energy in warmweather, increasing the kinetic energy of its particles and making itcontract. Trimming it gave it room to contract.

Answer 1

When the floor started to heat because of the warmer weather, the wooden floor started to dilate due to the increase in thermal energy, increasing its area. Since there wasn't space for it to expand, the floor started to buckle.

Then, trimming the edges of the floor was the solution, because this way the floor has space to expand due to dilation.

The statement that correctly states this information is found in option B.
