Afamily from minnesota turns off the heat and flies to florida for a winter holiday. when they come home, all of their water pipes have burst. what do you think happened?

The water pipes burst due to the expansion of water in them.

Water behaves in an anomalous manner. While most substances expand when heated and contract when cooled, water begins to expand at 4°C.

As a result of this, solid water is less dense than liquid water because it has more volume than liquid water.

Since solid water has more volume compared to liquid water, the pipes may no longer be able to contain the expanding water which has turned to ice leading to the bursting of the water pipes.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
