1. the sun produces 3.826 x 10^26 joules of energy every second as it combines smaller hydrogen atoms into larger helium atoms. what is the name of the process which allows for the production of so much energy? a) fission b) fusion c) heation d) photosynthesis 2. thorium-229 is the radioactive substance that gives lantern mantels their eerie glow. the half life of thorium-229 is 7340 years. if one mantel consists of 0.25 grams of thorium, how much thorium will remain after 14,680 years? a) 0.0625g b) 0.125g c) 0.25g d) 1.0g

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.

girl imma just put my comment here because i need a couple point okurrttt
