Which element has the coldest melting point?
This element is helium with a melting point of -272,20 0C.
What element has the lowest freezing and boiling point of all elements?
Helium melting point: -272,2 0C Rhenium boiling point: 5 596 0C
What is the point group for Benzene?
The point group for Benzene is D6h.
How can an element have freezing point at 200 degrees F?
an element's freezing point is the temperature at which the element becomes solid. some element's don't melt til heated to very high temperatures, and could therefore have a freezing point in the 100s of degrees.
The element with the highest freezing point is?
tungsten
What is the point group symmetry of a basketball?
D3h
What is the point group of CH2Cl2?
The Cs point group only has one symmetry plane. Cl2CH2 has two symmetry planes and one C2 axis. The mirror plane is perpendicular to the rotation axis, so this makes the point group C2h.
What is line and point symmetry?
Line symmetry = Reflection symmetry. Point symmetry = Rotational symmetry.
What is a point of symmetry and a line containing that point?
It is a line through the point of symmetry. In general it is not an axis of symmetry.
What is a figure that has point symmetry but not line symmetry?
The letters S and N have point symmetry but not line symmetry.
When an image has a point of symmetry then the line containing that point will be a line of symmetry?
false
When an image has a point of symmetry then any line containing that point will be a line of symmetry?
False
What has 2 lines of symmetry and no point symmetry?
rectangle
Does a triangle have point symmetry?
No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.
Which point of parabola is on the axis of symmetry?
Its extremum is on its axis of symmetry.
When an image has a point of symmetry then any line containing that point will be a line of symmetry true or false?
true
Are center of symmetry and inversion symmetry one and the same?
No, the centre of symmetry is a point usually somewhere in the middle of an object around which things like rotational or reflection occurs. Inversion symmetry is a sort of symmetry itself and not a point like the centre.
