A package of freshly picked sweet peas weighed 454g the peas were freeze dried and the recovered peas weighed 122g what was lost and what is the percentage of the compound lost

Water was lost from the peas. 73.1% of the mass of the original peas was water. The process of freeze-drying removes excess water and allows for food to be preserved while minimizing weight. So the answer to the 1st question is that water was lost. To calculate the answer to the second question, you simply divide the mass of water lost by the original mass, so (454 - 122) / 454 = 332 / 454 = 0.7312 = 73.1%

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.
