Early stages of carbon monoxide poisoning is often confused with seasickness or intoxication.
This is so because some symptons of carbon monoxide (CO gas) poisoning are: irritated eyes, headache, nause, weakness and dizziness. As you can see those symptons are common to seasickness and intoxitation.
Carbon monoxide (CO gas) is colorless and odorless, so it may be difficult to detect the exposure to it before having some symptons of CO poisoning, but it is serious and can result in death. The victim shall be conducted to an open place promptly to receive fresh air and carried to a hospital to receive treatment urgently.
The temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
480 = 150 × 0.033 × ∆T
480 = 4.95∆T
∆T = 96.9°C.
Therefore, the temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.

so,
80-35=45</span>
Answer:
1600cm3
Explanation:
From the question given, we obtained the following:
Density = 2.70g/cm3
Mass = 4.32kg :we need to convert the mass to grams
Mass = 4.32kg = 4.32 x 1000 = 4320g
Volume =?
Recall : Density = Mass /volume
Volume = Mass /Density
Volume = 4320/2.70
Volume = 1600cm3
