Answer: Although the best-known cause of a mass extinction is the asteroid impact that killed off the non-avian dinosaurs, in fact, volcanic activity seems to have wreaked much more havoc on Earth's biota. Volcanic activity is implicated in at least four mass extinctions, while an asteroid is a suspect in just one. Examples, of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.
46 is the answer. because if you add 26 and 20 that is the mass
If it is 60 Celsius that would conver to fare height by means of this equation; (1.8*60)+32°F
Which would come out to.... 140° Fahrenheit... Hardly seems like chilly conditions.
Answer:
Their average kinetic energy increases
Explanation:
The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.
Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.
- As the water in the pot heats up.
- The rice gains thermal energy.
- This causes the molecules of the rice particles to start vibrating.
- As the molecules vibrate about their fixed position, their thermal energy continues to increase.
- Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.
