Answer:
We can compare the both sample by taking into account the kinetic energy.
By increasing the temperature kinetic energy of gas molecules increased.
Explanation:
It is known that kinetic energy of molecules is increased by increasing the temperature.
We are given with two sample of hydrogen one is at 10°C and other is at 350 K.
Hydrogen sample at 10°C = 273.15 + 10 = 283.15 k
Thus one sample is at 283.15 K and other is at 350 K. So, the sample at higher temperature i.e 350 K will have more kinetic energy of molecules.
While the sample at 283.15 K will have less speed of molecule and kinetic energy.
Answer:
Exercise 1
a) 140 m
b) 100 m
c) 180 m
d) 140 m
Exercise 2
a) 20 yards
b) 30 yards
c) 20 yards
d) 55 yards
Exercise 3
a) 11 Kilometers
b) 7 Kilometers
Explanation:
Exercise 1
Distance from B to C = 140 m
Distance from to D = 100 m
Total distance = 100+40+40 = 180 m
Total displacement i.e. distance between A and D is 140 m
Exercise 2
a) Distance from B to C = 35 -15 = 20 yards
b) Distance from C to D = 5 + 35 = 30 yards
c) Distance from B to D = 5 + 15 = 20 yards
d) Displacement = 5 + 50 = 55 yards
Exercise 3
a) The total distance travelled = 5 + 2 + 4 = 11 Kilometers
b) Displacement = 5-2 + 4 = 7 Kilometers
Answer:
Explanation:
During that process of being exposed to air and water while being left outside or in the elements for an extended period of time, a variety of different types of rusts can form, but the most common form is Fe2O3. Rust only forms on the outside of a metal surface because it requires exposure of oxygen and water to rust.
Answer: because ch4 is not considered a acid they said it is too weak
