Zippy decides he needs a drink to wash down the cold Pring Pongs. There are two 355 mL cans of Kookie Cola in the mini-bar.
Lady bird [3.3K]

20.7 Degree celsius is the temperature of Zippy's room.

Explanation:

The initial conditions of the kookie cola will be depicted by P1,V1 and T1.

P1= 36.5 psi or 2.4816 atm

V1= 355ml or 0.35 L

T1= 275.5K

The final conditions are given P2,V2 and T2

P2= 38.9 psi or 2.6469 atm

V2 = 355 ml or 0.35 L

also the solubility of the carbon dioxide does not change with temperature.

Applying the formula

P1VI/T1=P2V2/T2

since volume does not change and remains constant.

It can be written as:

P1/T1=P2/T2

= 2.4816/275.5=2.6469/T2

T2= 293.85 K

  • An experiment conducted in the 1960s proved that most parts of DNA are composed of long strings of repeated sequence which does not code for proteins.
  • The process involves in coding for a protein are the transcription of DNA to RNA, then translation followed by protein synthesis. There are enzymes involved in these processes.
  • As per the latest study, it states that only 1 per cent of genes code for proteins rest 99 per cent is called the non-coding DNA.
