Note that "hyperbole" means exaggeration. So for your sentences:
- sun: The sun is so hot, that i'm going to physically melt. (obviously it's not going to be that hot, or else you won't live to say the sentence)
- school: School is like a torture chamber. (obviously it isn't one)
- car: This car is so expensive, i'd have to sell an organ to buy it. (obviously it isn't THAT expensive).
- cheetah: This cheetah runs so fast, he runs faster than an jet fighter (extermely doubtful).
hope this helps
