Antonio observes the weather one afternoon. He claims that thunderstorms are likely. Which observation provides evidence that supports this claim? There is a light wind. The temperature is 23 °C (75 °F). The winds are blowing from the east. The clouds are mainly cumulonimbus.

The clouds are mainly cumulonimbus.

Explanation:

A Thunderstorms is a relatively small storm but usually quite intense. As little as 10 percent of thunderstorms may be considered severe globally. These severe thunderstorms may lead to high winds, hail, flash floods, and tornadoes. Severe thunderstorms may be injurious to health and even lead to fatalities.

Thunderstorms are produced by cumulonimbus clouds, hence Antonio's observation of a cumulonimbus correlates well with the prediction of a thunderstorm.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
