Copper is current voltage above 40 or 200 . copper useful for motor and some medicine
Answer:
1.20 × 10³ torr
Explanation:
Step 1: Given data
- Initial pressure (P₁): 822 torr
- Initial temperature (T₁): 325 K
- Final temperature (T₂): 475 K
Step 2: Calculate the final pressure of the gas
Considering the constant volume, if we assume the gas behaves ideally, we can calculate its final pressure using Gay-Lussac's law.
P₁/T₁ = P₂/T₂
P₂ = P₁ × T₂/T₁
P₂ = 822 torr × 475 K/325 K = 1.20 × 10³ torr
Because sometimes people get different answers because some observe and some actually test and use there senses
Answer:
Here are the most common formulas associated with a sphere:
The volume (V) of a sphere is the amount of 'stuff' that could fit inside the sphere. Usually, when discussing volume, it is in terms of a liquid or gas. An example would be, 'What is the volume of air that can fit inside a basketball?' The formula for volume is:
V = (4/3?r^3
Surface area is just what its name implies: it's the area of the surface of an object. So, if you could cut open the basketball from the previous example and lay its surface out flat, you could see the surface area? This is useful for determining how much material would be needed to cover the sphere in question. The formula for surface area is:
SA = 4?r^2
Examples
Using our formulas, let's take a look at some example problems using spheres:
1.) What is the volume of a ball with a radius of 6 inches? (We'll use 3.14 for pi and round our answer to the nearest .10.)
