Answer:
When two people "collide" and one of them is carrying the virus then the other person starts carrying it. This is why we need to social distance so it doesn't spread.

Answer:
Explanation:
Hello,
In this case, since we can consider hydrogen gas as an ideal gas, we check the volume-pressure-temperature-mole relationship by using the ideal gas equation:
Whereas we are asked to compute the moles given the temperature in Kelvins, thr pressure in atm and volume in L as shown below:
Best regards.
That would be cause part of the sodium is pure and that means it still kind of has it properties when it was an element and that its i think.
It has 49 electrons as well. The amount of protons and electrons are equal.
Answer:
Option e is correct
The heat required to increase the temperature of copper metal by 1 degree is 0.754 j
.
Explanation:
Given data:
specific heat of copper = 0.377 j/g.°C
Heat required to increase temperature = ?
Mass of copper = 2.00 g
Change in temperature = 1°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Q = m.c. ΔT
Q = 2 g× 0.377 j/g.°C × 1°C
Q = 0.754 j
The heat required to increase the temperature of copper metal by 1 degree is 0.754 j
.
