A steeper concentration gradient means that more of the water molecules are able to interact and transfer kinetic energy, so the random motion causes more water molecules to move across the membrane. ]]> 2018-09-24 14:50:41 UTC https://padlet.com/seclavea/egglab2/wish/285059783 https://padlet.com/seclavea/egglab2/wish/285060302 Question: Why does a steeper concentration gradient lead to a faster rate of diffusion?

A steeper concentration gradient leads to a faster rate of diffusion because molecules have a tendency to spread out due to their kinetic energy, and a steeper concentration gradient leads to the movement of more molecules, implying a faster rate of diffusion.]]> 2018-09-24 14:51:32 UTC https://padlet.com/seclavea/egglab2/wish/285060302 wli33 https://padlet.com/seclavea/egglab2/wish/285061109 When the concentration gradient increases the kinetic energy does as well because there are more particles to bounce around on each other and diffuse with the concentration gradient, and when the concentration gradient is lower the rate of diffusion is also lower 
 because there is less kinetic energy and thus is closer to a state of equilibrium (in 5% salt solution egg lost 0.14g in 10 min)]]> 2018-09-24 14:52:23 UTC https://padlet.com/seclavea/egglab2/wish/285061109 axli https://padlet.com/seclavea/egglab2/wish/285062091 The concentration gradient affects the rate of diffusion because substances diffuses down its concentration gradient, from an area of higher mass to an area of lower mass. Because there is more kinetic energy in the egg when more salt molecules are in the cell, there is more chance of collision between the molecules which will push it to less dense areas, making the rate of diffusion faster. ]]> 2018-09-24 14:53:32 UTC https://padlet.com/seclavea/egglab2/wish/285062091 jwli2_2 https://padlet.com/seclavea/egglab2/wish/285062370 Because the concentration gradient is larger, there would need to be more energy in order to move all the molecules to reach equilibrium, therefore increasing the rate of diffusion. ]]> 2018-09-24 14:53:55 UTC https://padlet.com/seclavea/egglab2/wish/285062370 https://padlet.com/seclavea/egglab2/wish/285064351 This means that the water did not exit the cell as much in the second experiment because its gradient wasn't as large a gap. the 10% had more energy because of how much salt dissolved versus the 5%, so the 10% lost more mass because it had more kinetic energy to create a hypo-tonic solution.]]> 2018-09-24 14:56:26 UTC https://padlet.com/seclavea/egglab2/wish/285064351
