Boyle's Law
In contrast to others definitions of this, the actual Boyle's law, commonly referred to as the Boyle-Mariotte Law (Mariotte's law in France, describes the relationship between pressure and volume of a confined gas. The equation is usually written as PV = k where pressure multiplied by volume equals some constant k. The law in simplest terms states that when the temperature of a given mass of confined gas is constant, the product of its pressure and volume is also constant. If boyle's law is comparing the same substance under two different sets of conditions, the law can be expressed as P1V1 (1 being subscript), = P2V2 (2 being subscript). This means that as volume increases, the pressure fo a gas decreases proportionally, and vice versa. Boyle's law can be applied, and is applied to divers. Such that if a diver takes a lung full of air while they are underwater, that air will expand in his lungs as he rises to the surface. If the diver holds his breath, or ascends too rapidly, such as comparable to a cork being opened in a quick motion, the expanding air can thereforth rupture his lungs. This is reason number one why exploring the ocean can be dangerous, save whatever creatures co-exist in the deep blue. This law can be used in tandem with Charles' Law, Gay-Lussac's Law, Henry's Law, and Dalton's law. Boyle's Law, Charles's Law, and Gay-Lussac's law form what is known as the Combined Gas Law, or the General Gas Equation.
The Urban Dictionary Mug
The mug I ordered was exactly as described on the site. The shipping was fast as well. I will buy from these people again.
Cute mug, arrived promptly in great condition. I like how you can choose background color & change wording. Will feel cheerful when drinking my coffee in this :)
Heavenly Mug This mug has been sent from the heavens. I'm too broke to buy it. But one day... I will. I will be mugged, dammit!
Why am I here? I don't know how I got here, but I can't stop writing weird things on the cup...😅 Help me. I have a test to study for. A family. Also, if I wasn't broke I would buy 10,000 of these mugs. They look highly entertaining. Love this website, and I probably will fail the test. 🙃
I took time designing it but wasn't sure, online tools being what they are, that what I was seeing was for sure what I'd get. Very much appreciated the customer service communication which verified that what I'd designed was what I wanted, and the shipping was quick too.
Item came on time as promised
Came within a week and it's exactly what I ordered, my friend will love it!
Sus cup I bought the sus mug for the sus king Daequan
Good quality, packaging shipped well, arrived quickly.
My mug came in broken but Urban Dictionary replaced it at no extra charge!
Excellent mug excellent service
this is the best for coffee and hot coco especially if you make the hot coco in it then pour it on your significant other and do body shots 😋🥱
I can pass away peacefully. This mug is everything I’ve ever needed and more. Fat thank you, Urban Dictionary. <3
I was really excited to receive this mug and when it did come it was perfect quality. My only complaint is that the color I choose was green teal but it came in yellow.
As always, easy to order and not-too-long of a wait for the finished product to arrive. It’s well-printed, and very sturdy. A great gag present for wedding party members.
The mug , color and saying are perfect! PMEO is what I say at work everyday. It has become a favorite saying for my coworkers when things go haywire!
Quality and style are outstanding relative to price point.
Love it! It is my favorite mug. Easy to hold because of its shape and weight. Now my go-to mug.
My wife is truly beautiful and this cup was perfect for her.
Awesome mugs! My GF laughed her ass off, lol!!!
