Density depends on both the mass and the volume of an object. If you cut a bar of gold in half, you would have two bars with half the mass of the original bar. However, each bar would also have half the volume of the original bar. The density of gold does not change.

Answer:
121 K
Explanation:
Step 1: Given data
- Initial volume (V₁): 79.5 mL
- Initial temperature (T₁): -1.4°C
- Final volume (V₂): 35.3 mL
Step 2: Convert "-1.4°C" to Kelvin
We will use the following expression.
K = °C + 273.15 = -1.4°C + 273.15 = 271.8 K
Step 3: Calculate the final temperature of the gas (T₂)
Assuming ideal behavior and constant pressure, we can calculate the final temperature of the gas using Charles' law.
V₁/T₁ = V₂/T₂
T₂ = V₂ × T₁/V₁
T₂ = 35.3 mL × 271.8 K/79.5 mL = 121 K
The functions of the ears are:
I. Hearing by collecting and processing sound waves
II. Keeping our balance when we turn or bend over; option A
<h3>What is the function of the ear?</h3>
The ear is one of the five sense organs in the body.
The sense organs are the organs which receive external stimulus and send it to the brain for processing and response.
The other sense organs are:
- the eye
- the nose
- the skin
- the tongue
The functions of the ear are for hearing and for balance.
In conclusion, the sense organs function to receive stimulus and send them to the brain.
