Clearly H2 is in gaseous state as could be seen from (g) written with it which tells state of the product
Answer: look at the close because that is the answer
Explanation:
Answer: The correct answer is: the water can transfer heat to your arm more quickly than the air.
Explanation: The heat is transferred from the air or water to your arm through convection. The convective heat transfer coefficient of water is higher than the air's, so, even though the temperature of boiling water is lower, the heat will be transferred more efficiently to the other surface, in this case, the hand.
First of all there nothing exists something like SSA congruence criterion, It is SAS Congruence where the sides of a Triangle and the angle between them is exactly same to the other two sides and angle between them of another triangle.
So the correct option is D.
Explanation:
If the Triangle has two sides equal, so the two angles there are equal. Also the other angle be some other definite angle. So
45+x+x=180(Considering definite angle to be 45)
2x=135
x=67.5
So there is only one solution to the triangle.
The answer to this question is 4-7
