Heat can be transferred through conduction, convection, and radiation. what is necessary in order for heat to be transferred by conduction?

The objects must be in direct contact with one another.

Explanation: "Heat is transferred by conduction when objects are in direct contact with one another.

Heat transfer through space is radiation, and heat transfer through currents in liquids or gases is convection"

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
