Answer:
Explanation:
428 x 10³ Pa = 4.28 x 10⁵ Pa = 4.28 atm
We shall use the gas equation
P₁V₁ / T₁ = P₂V₂ / T₂
7.66 x 10 / ( 273 + 27 ) = 4.28 x 30 / T₂
.255 = 128.4 / T₂
T₂ = 503.53
= 503.53 - 273 = 230.53⁰C .
Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km). The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system.
Answer:
100,000,000,000
Explanation:
Given that :
1 hubble space telescope pointed at 1 section of the sky reveals 10,000 distinct galaxies ;
Number of sections from which observation is to be made = 10,000,000
Number of distinct galaxy per section = 10,000
Number of galaxies that would exist in the known universe :
Total number of galaxies in the known universe :
Number of galaxies per section * number of sections
10,000 * 10,000,000
= 100,000,000,000s
Answer:
Difference in temperature
Explanation:
Temperature is the degree of hotness or coldness of a body. The difference in temperature between two bodies enables heat transfer from the hotter body to the colder one. If two bodies are at the same temperature, heat transfer will not occur between them. This why in the vicinity of hot water, a cold water becomes warmer.
