Answer:
hey, hope this helps :)
Step-by-step explanation:
1. Matter changes state because of physical pressure and temperature; properties do not change.
heating gives molecules energy that causes them to vibrate faster, breaking their bonds and melting.
3. Heat energy that helps break the molecular bonds of a solid is heat of fusion
4. The temperature at which a liquid turns into a gas is the boiling point.
5. sublimation is when a solid turns straight into a gas.
Answer:
the answer is B
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Gradient is the same as slope to get your answer follow this formula y2 - y1 divided x2 -x1 in this problem it will look like this
4 - (-4) /1 - (-1) =
8 / 2 =
= 4
I hope this helps!!
Answer with explanation:
The meaning of bijection for two sets X and Y is each and every element of X is uniquely related with element of set Y and when you take the inverse mapping every element of set Y is uniquely related with each and every element of Set X.
The two sets given are
X=(0,1]---------Semi open or Semi closed Set
Y=(0,1)---------Closed set
Between any two real numbers there are infinite number of real numbers.So cardinal number of both the sets is infinite.
There can be infinite bijection between these two sets as both sets have infinite number of elements.
X Y
0.1 ------------- 0.01
0.2 ------- 0.02
0.3 -------- 0.03
0.4 --------- 0.04

Answer:
Step-by-step explanation:
Given
Initial Temperature = -5F
Change (by noon) = 12 degrees
Required
Determine the temperature at noon
The temperature by noon is calculated as thus;
Substitute values for Initial temperature and change
Hence, the temperature at noon is 7F
