The 17 is a colder plug with a heat range of 7. The 19 is hotter with heat range of 9. The higher heat range is preferable for colder climates. While the 17 is for warmer areas.
Every bottle has different heat. Higher the number hotter the tabasco
Yes, heat DOES transfer from the colder to the hotter body but there is a NET heat transfer from the hotter to the colder body.
No heat does not flow from colder to hotter. It flows from hot to cold.
The higher number is hotter, so the R45TS is hotter than the R44T. If your heads have tapered seats, then you would need the TS, which is available in the same heat ranges as the T.
heat range. 7 is a "hotter" plug. That means it transfers more heat to the cylinder head during operation.
When you heat ice it takes in the heat and its temperature rises until it reaches melting point. It then takes in heat without getting hotter. When it's all melted, then the water that it now is gets hotter and hotter. When it reaches boiling point more heat will simply turn it into steam without it getting hotter. If you keep adding heat to the steam then it will get hotter. The heat that you have to add to something to change its physical state (i.e. from solid to liquid or liquid to gas) but without it actually getting hotter, is known as 'latent heat'.
By the SUNS ENERGY. (Which makes it hotter and hotter.)
"Heat" is a noun and a verb and, as such, does not have a comparative form.
Heat travels from a hotter place to a colder place.
Temperature difference or "heat range" is that a "hot" spark plug has a long insulator with more surface area exposed in the combustion chamber. This spark plug will stay hotter, helping to burn off residue and deposits. A "cold" spark plug has very little exposure of its ceramic insulator to the combustion chamber. This spark plug will run cooler, however the 25 and 26 are not heat ranges or temperature indicators. You can read more in the related link.
