Why is tape attracted to my skin? Give explanation

Chemistry
1 answer:
shutvik [7]3 years ago
5 0

Answer:

Since the tape has extra electrons, it has a negative charge. When you move your finger close to the tape, electrons in your skin are repelled and move away. This makes the skin on your finger tip have a slight positive charge. Since positive and negative attract, the tape moves toward your finger.

Mekhanik [1.2K]

Respuesta:

5 L

Explicación:

Paso 1: Información provista

  • Presión inicial (P₁): 1,5 atm
  • Volumen inicial (V₁): 20 L
  • Presión final (P₂): 6 atm

Paso 2: Calcular el volumen final del gas

Si asumimos temperatura constante y comportamiento ideal, podemos calcular el volumen final del gas (V₂) usando la Ley de Boyle.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁ / P₂

V₂ = 1,5 atm × 20 L / 6 atm = 5 L
