I need to find the new volume. I got 820.6 mL for my answer but I would like some to double check.

The correct answer is 820,6 ml

Explanation:

We apply Charles's law, where for a constant pressure and mass, the volume and temperature vary directly proportionally:

V1/T1= V2/T2

V2= (V1/T1)xT2= (950ml/345K)x 298K =820,579701 ml

The new volume is 820.6 mL

Explanation:

Step 1: Data given

Initial volume of the balloon = 950 mL = 0.950 L

The initial temperature = 345K

The temperature is decreased to 298 K

Step 2: Calculate the new volume

V1/T1 = V2/T2

⇒with V1 = the initial volume = 0.950 L

⇒with T1 = the initial temperature = 345 K

⇒with V2 = the new volume = TO BE DETERMINED

⇒with T2 = The decreased temperature = 298 K

0.950 L / 345 K = V2/ 298 K

V2 = (0.950/345)*298

V2 = 0.8206 = 820.6 mL

The new volume is 820.6 mL

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
