Water expands when it freezes, so if you fill the balloon too much, it will burst as the water expands. The pressure from the water causes the air to compress inside the balloon. The deeper the balloon is taken into the water, the greater the pressure, and therefore, the smaller the balloon will become. Molten balloon could be fused to the inside surface of the oven. The water will very slowly hear. A balloon full of water might be 2 litres. Put on your safety glasses.
Hold the balloon 30—50 cm over the top of the flame and slowly move the balloon closer and closer to the flame until it pops. Note: The flame does not need to touch the balloon before the heat melts the latex and it bursts.
Explanation:The tank can hold enough helium because the gas in the tank is under tremendous pressure. Gas will contract under high pressure, and expand under low pressure.
When the helium goes into the balloons, it occupies much more space because there is less pressure in the balloons than in the tank. What is the mass of the lid? Collect data: With the temperature held constant at K, use the Select massslider to place weights on the lid. If a sealed container of gas were placed in a fire, the temperature and pressure of the gas would increase until the container broke or exploded.
If you heat a gas you give the molecules more energy so they move faster. When gases in containers are heated, their molecules increase in average speed. The gas is therefore under greater pressure when its temperature is higher. This is why fires near sealed gas cylinders are extremely dangerous. The balloon will inflate. If you put plaster over a water balloon and freeze it, the water balloon will bulge out. Nothing happens to the metal, there may be sparks from the metal to the housing of the microwave, the microwave may short out.
The balloon will be broken. It expands until the balloon melts. Microwave blows up or goes on fire. If you put a mentos in the diet coke and put it on the microwave, it will cause a chemical reaction causing your microwave to explode.
The balloon shrinks because the molecules are moving slower. The balloon's size and density will increase due to temperature change[:.
It will float into the air. It arcs. If it's the only thing in the microwave, it's bad for the magnatron. The lamp will explode. Log in. Study now. See Answer. Best Answer. Study guides. Science 20 cards. Who is known as the first African American scientist. What is Luis Alvarez's cultural background. What was Benjamin Banneker's ethnic background. Which scientist used mathematical knowledge to calculate the exact measurement of the meter.
Genetics 20 cards. What are chromosomes made of. As helium molecules heat they start moving and expanding, this movement puts pressure on a latex balloon and can cause it to expand and pop. On a hot day this movement will also speed up the float time of your balloon and significantly reduce it from hrs to hrs for standard size balloons.
Standard size latex filled helium balloons stay afloat for approx 8 — 12 hours, whereas helium filled balloons float for days. If you want your latex balloons to float longer there is a useful product that you can buy Helium Hi-Float Treatment Kit which helps the balloons float up to 25 times longer! Our surrounding is filled with air.
Now it is known that the density of hydrogen and helium is lighter than that of air. So, if a balloon is filled with any of these gases, the balloon will float. Since we are talking about floating balloons without helium, we would consider Hydrogen gas here to fill the balloon. Begin typing your search term above and press enter to search.
