Article: To calculate the density of water you will need a graduated cylinder, a scale or balance, and water. Graduated cylinders are special containers that have lines or gradations that allow you to measure a specific volume of liquid. In order to find the density, you have to know the mass and volume of the liquid in question. You will use the graduated cylinder to obtain the mass of the water, but you have to subtract out the weight of the graduated cylinder so you know you’re only measuring the mass of the water itself.  Turn the balance on and make sure it is set to zero. Place the dry, empty graduated cylinder on the balance. Record the mass of the cylinder in grams (g). For example, let’s say the empty graduated cylinder weighs 11 grams. It doesn’t matter how much water you add, but be sure to note the exact amount. Read the volume by looking at the cylinder at eye level and recording the volume at the bottom of the meniscus. The meniscus is the curve of the liquid that you’ll see when you look at the water right at eye level.  The volume of water in the graduated cylinder is the volume you will use for the density calculation. Let’s say you filled the graduated cylinder with 7.3 milliliters (mL) of volume. Make sure the balance is set to zero and weigh the graduated cylinder full of water. Be careful not to spill any of the water out of the top when you weigh it.  If you do spill the water, take note of the new volume and re-weigh the water-filled graduated cylinder. For example, let’s say the full graduated cylinder weighs 18.3 grams. To get the mass of the water only, you must subtract out the weight of the graduated cylinder. The result is the mass of the water in the cylinder. In our example, the mass of the graduated cylinder is 11 g and the mass of the cylinder full of water is 18.3 g. 18.3 g – 11 g = 7.3 g, therefore the mass of the water is 7.3 grams. Using the equation density = mass/volume, you can determine the density of water. Plug in the values of mass and volume you determined and solve.  Mass of the water: 7.3 g Volume of the water: 7.3 mL Density of water = 7.3/7.3 = 1 g/mL

Gather your materials. Weigh the empty graduated cylinder. Fill the graduated cylinder with water. Weigh the water-filled graduated cylinder. Subtract the weight of the empty cylinder from the full cylinder. Calculate the density by dividing the mass by the volume.
Article: Before you decide to travel in an airplane with your pet, it is important that you consider all the risks involved in this type of travel. Flying can be terrifying for animals, and extreme conditions cause animals to die on flights every year. Do your research and consider reconsidering your decision to fly with your pet. Many airlines and countries require that your pet have proper health clearances before traveling. This often includes a certificate of health along with proof of vaccinations. Check with your air carrier and country of origin and destination to get information on what health clearances are necessary for pets. Once you do this, set up an appointment with your veterinarian to ensure your pet is properly certified for travel. You should, at all costs, avoid flying with your pet in the cargo hold. Extreme temperatures, lack of pressurization, and elevated stress levels contribute to numerous deaths of pets flying in the cargo hold of planes each year. Instead, find an airline that will allow you to fly with your pet in the cabin. You should take a direct flight, and make sure you are on the same flight as your pet. Your pet should be wearing a collar that will not get caught in its carrier, and the carrier should have a travel label attached to it with your information. You should also notify the flight attendants that your pet is traveling in cargo, and carry a current photo of your pet with you. If you are flying with your pet during the holidays, it is important that your pet does not eat in the hours preceding the flight. This will help prevent your dog from vomiting during the flight if they experience motion sickness. It will also limit your pet’s need for a potty break during air travel. If your pet is traveling in an airplane, it will have to spend the duration of the flight in its travel carrier. The last thing you want is for your pet’s paws to get caught in the carrier due to unruly nails. Take time before you travel to clip your pet’s nails. It is important that you refrain from drugging your pet before or during air travel. Under no circumstances is it safe to sedate your pet before or during air travel. Sedated pets can have extreme reactions to pressurized aircraft, and sedating your pet increases the risk of death.
Question: What is a summary of what this article is about?
Understand the risks of air travel. Get the proper health clearances. Choose cabin travel if possible. Take precautions if your dog flies in the cargo hold. Do not feed your pet for 4-6 hours before the flight. Clip your pet’s nails before air travel. Do not give your pet tranquilizers.
