How does the sharklet film protect against bacteria?
babunello [35]

Answer:

The sharklet film creates a phenomenon reffed to as  mechanotransduction.

Explanation:

It was discovered that sharks do not experience fouling , their skin is made in a distinct manner with diamond patterns that will discourage micro organism from settling on it.

Through the process of mechanotransduction, mechanical stress is created to the bacteria whereby they cannot attach themselves to the surface because it makes them to produce more energy to settle on the surface thus they may keep off from the surface. In this manner, bacteria is inhibited from attacking these areas protected by the sharklet film.

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 8.10kg of water at 33.9 degree
Anuta_ua [19.1K]

Answer:

309.1K

Explanation:

Step 1: Convert the flown heat to Joule

We will use the relationship 1 kJ = 1,000 J.

69.0kJ \times \frac{1,000J}{1kJ} = 69.0 \times 10^{3} J

Step 2: Convert the mass of water to gram

We will use the relationship 1 kg = 1,000 g.

8.10 kg \times \frac{1,000g}{1kg} = 8.10 \times 10^{3} g

Step 3: Convert the initial temperature to Kelvin

We will use the following expression.

K = °C + 273.15 = 33.9°C + 273.15 = 307.1 K

Step 4: Calculate the final temperature

We will use the following expression.

Q = c \times m \times (T_f - T_i)

where,

  • Q: heat
  • c: specific heat capacity
  • m: mass
  • T f: final temperature
  • T i: initial temperature

T_f = \frac{Q}{c \times m} + T_i = \frac{69.0 \times 10^{3}J }{4.18J/g.K \times 8.10 \times 10^{3}g} + 307.1K = 309.1K
