TRUE LIES: There are many misconceptions regarding fire. A person must equip himself with factualinformation to guarantee safety. Not all shared information is true. So, can you spot them?Direction: Below are statements about basic information on fire. On your answer sheet, write TRUE if thestatement expresses a correct idea, otherwise write LIE.4. Fire is a thing, not an event.5. Assuming stable fuel, heat, and oxygen levels, a typical house fire is constant in size every minute until the firedies down.6. Earth is the only known planet where fire can burn.7. Water can be produced by fire.8. Using concentrated sunlight, ancient Greeks were able to start fire. A parabolic mirror that focuses solar rays isstill used to ignite the Olympic torch.9. Among the stages of fire, the last stage which is the “decay stage” takes the longest time to finish.10.All fire extinguishers are multipurpose, meaning each one can put out all types of fire caused by any material.NOTE: JUST THE ANSWER ONLY NO…

The average time for oxygen molecules to diffuse 0.5 mm is 20 seconds. How long would it take for oxygen molecules to diffuse 1.0 mm? A. 40 s B. 14 s C. 80 s D. 30s

Dr. Wong's assistant made the observations below while heating a sample of solid hydrogen. Using the data and observations in the table below, create a heating curve for hydrogen that Dr. Wong can reference during his laboratory testing. Be sure to include and label the following items in your heating curve: Create temperature and time intervals that are appropriate for the data. Don't start the temperature on the graph at 0 °C because the time intervals will be too large for the hydrogen data. Label the melting and boiling points on the curve. Label the three states and the two transition phases on the curve.   Heating data: Time (Minutes) Observations 0:00 Hydrogen is a solid at −263 °C. Heat is added to sample. 2:43 Hydrogen begins to change into a liquid at −259 °C. 6:15 Temperature of the liquid begins to increase. 10:36 Hydrogen begins to form a gas at −253 °C. 14:01 Temperature of the gas begins to increase. 18:00 Final temperature of hydrogen gas is −245 °C.…

CFCs are family of compounds containing the elements carbon, fluorine and chlorine. Which of the following statements is NOT true about CFCs? a. Ozone is attacked by chlorine atom that breaks free from the CFC molecule b. CFCs were to be found in aerosol sprays and refrigerants c. CFCs can remain in the atmosphere from up to 100 years d. Each CFC molecule destroys a single ozone molecule

hello can you plz help me plzzz

Part B What are each of the following observations an example of? Drag the appropriate items to their respective bins. • View Available Hint(s) Reset Help When person applies perfume in one corner of the room you can smell its fragrance in another room. When a coworker microwaves popcorn, you can smell the vapors in your office 5 minutes later. A balloon in a constant environment gets smaller and smaller over the course of a week as gas leaks through small holes in the rubber. When you drive over a nail the volume of the tire decreases slowly over time as air escapes through the hole. Diffusion Effusion
