Answer:
Explained below
Explanation:
The human body has a normal core temperature of around 37°C to 38°C.
Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.
If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.
Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.
Firstly calculate the grams in the last 8 percent before moving onto the pyrite section.
50.8x0.08=4.064g
We know that iron ore in this case has 92 percent pyrite which contains 46.5 percent iron so we do 50.8x0.92=46.736g from this we need to find 46.5 percent of the iron content in the 92 percent pyrite section then add this answer to the 8 percent of iron ore we found at the start.46.736x0.465=21.73224g
21.73224g+4.064=25.79624g of iron ore 25.8g(3sf)
<span>Body fossils can mostly be found in things like rocks and minerals deep in the ground or in mountains and caves. They can also be found in quick drying substances such as for example tar pits or basically anywhere where there has been historically chance of encountering a fossil. You can also find them in peat, so that's 4 then.</span>
Answer:
*Engineers can design better bridges because they know how metal changes shape.
*Scientists can easily classify mixtures of unknown substances.
Explanation:
Tensile strength and the properties of mixtures are physical properties because the substances are not changed into different ones.
A. and C. are wrong. Combustion and other reactions are chemical properties because the substances are changed into different ones
