Why does it take more time for a larger sample of water to freeze?

The greater the amount of water that there is it will take longer for the water to freeze because more heat has to be dissipated into the environment

Explanation:

The greater the mass of water, the more heat has to be dissipated into the environment and the longer it will take to freeze. The greater the surface area of the water, the faster the water will lose its heat and freeze.
