Answer:
Q = 5671.05 J
Explanation:
Given data:
Mass of metal = 525 g
Initial temperature = 32.0 °C
Fina temperature = 43.0 °C
Heat absorbed by metal = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
specific heat capacity of metal X = 0.982 J/g.°C
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
ΔT = 43.00°C - 32.00°C
ΔT = 11.00°C
Q = 525 g × 0.982 J/g.°C × 11.00°C
Q = 5671.05 J
Answer:
B. CO2
Explanation:
Because its a neutral compound hence lacks any form of dipole dipole interaction
The nucleus is the centre of an atom, and it's assumed that is where the proton and neutron are located. Electrons are though to orbit around the nucleus, so the answer is (1) an electron
