P,T,Y refers to the set of points which are collinear and is therefore denoted as option C.
<h3>What are Collinear points?</h3>
This is commonly used in geometry and refers to the set of points which lie on the same straight line and are always close to each other when compared to other points. It is possible for them to appear on different planes only and the value by the triangle from the three points is usually zero.
In the example give, only P,T and Y are the points which lie on the same line while other options have points which lie on different lines thereby making them incorrect.
This is therefore the reason why option C was chosen as the most appropriate choice.

#SPJ1
is the product of the mass and velocity of an object, quantified in kilogram-meters per second.
Change of appearance, change in size and shape of a substance, change in phase of a substance, and I'm pretty sure expansion/contraction is an answer, too.
The answer is C. Valence Electrons
<u>Answer:</u> The amount of energy required to raise the given amount of temperature is 6400 J
<u>Explanation:</u>
To calculate the heat absorbed by the lead, we use the equation:
where,
q = heat absorbed
m = mass of lead = 200 g
c = heat capacity of lead = 0.128 J/g°C
= change in temperature = 250°C
Putting values in above equation, we get:
Hence, the amount of energy required to raise the given amount of temperature is 6400 J
