More bonds have to be broken, and that requires more heat input.

This will calibrate the apparatus change in temperature against a given heat input.

And he had never been comfortable with such a major element of the terraforming's heat input being so fragile.

Your heat input by radiation will depend upon where you are in space.

The level of heat input also affects weld quality.

Pulsed current is particularly useful for these applications, as it helps limit the heat input.

With less heat input, the net result was that the reactor would cool.

The source of energy in a heat engine, is a heat input.

During very large activity, however, this heat input can increase substantially, by a factor of four or more.

It becomes very small so that the sample's increase in temperature for a given heat input may be relatively large.
