Answer:
The new volume of the balloon be 
.
Explanation:
We have,
Initial volume is 556 cm ³
The temperature of the balloon decreases from 278 K to 231 K.
We need to find the new volume of the balloon if the pressure is constant.
The Charles law states that at constant pressure, the volume of gas is directly proportional to its temperature i.e.
, P is constant
So, the new volume of the balloon be .
Answer:
Explanation:
You are not really helped by what is hold the liquid. Beakers and cylinders come on a lot of sizes. I hate to be crabby about things like that, but you really need to be aware that the question is slightly flawed (not your fault).
The beaker, you'd be like to get 1 sig digit. You have to be awfully careful about claiming more. So the and is 50 mL, but that mL is a guess and the 50 is not totally accurate, but what would you say the second digit is? 48 or 47? You don't really know. Maybe even 49.
The graduated cylinder is a little better. Read the bottom of the meniscus (the bottom of the 1/2 bubble). I think you can get 2 sig digs., so the answer is 36 mL. But everything also depends on what you have been told.
Predict the effect of each of the following on the indicated equilibrium system in terms of which reaction will be favored
H2(g)+Cl2(g)<=>2HCl(g) +184 kJ addition of Cl2 removal of HCl increased pressure decreased temperature removal of H2 decreased pressure addition of a catalyst increased temperature decreased system volume
im sorry i am not sure if this is the answer you are looking for
Answer:
Condensation is when heat turns to water vapour
Melting is when solid turns to liquid
Freezing is when liquid turns to solid
Sublimation is when solid turns to gas without passing through the liquid state
