1. When you first opened the bottle of coke the pressure of gas in the coke (increased/decreased) and the dissolved gas( stays in/leaves) the coke. 2. When you placed the coke in hot water , the pressure of gas in the coke (increased/decreased) and the dissolved gas( stays in/leaves) the coke 3. Therefore to increase the solubility of a gas in a liquid ( that is to make a gas more soluble in a liquid) you should( increase/ decrease) pressure ( increase/ decrease) temperature 4. Adding salt ( increase/ decrease) the solubility of gas in the liquid. This is due to the nucleation sites on the salt( rough/smooth) surface where the gas forms. (nucleation sites are places where a gas can make bubbles)
