Given that the specific heat of iron is 0.450J/g:K find the final temperature after 103.4) of energy is removed from 98.2g of iron at 87.3°C.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Sheela and her brother hari were sitting in the living room, watching tv. suddenly hari said that he thinks something is burning in the other room. how did he get the burning smell?
