Taryn has a 90-gram sample of ethanol, which has a specific heat of
2.46 j/g°c. how much heat energy is required to raise the temperature of her sample from 20°c to 35°c?

1. they vary with a higher number because boiling is way hotter than melting

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
