Answer:
Q = 940.5 j
Explanation:
Given data:
Mass of iron = 95 .00 g
Initial temperature = 36.0°C
Final temperature = 58°C
Heat lost = ?
Solution:
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
Specific heat capacity of iron = 0.450 j/g.°C
ΔT = T2-T1
ΔT = 58°C-36.0°C
ΔT = 22°C
Q = m.c. ΔT
Q = 95.00 g × 0.450 j/g.°C × 22°C
Q = 940.5 j
Answer:
I noticed that my skin cells have little tiny holes all over the area I am looking at. I also notice a little bit of dry skin on the skin cell. Not only do I see little holes and dry skin but I also see different types of skin. Rough skin and smooth skin. That is what I see.
Explanation:
Its D, because planets closer to the sun go around faster
The molar mass of O2 is 32g/mol. So the mol amount of these O2 is 56/32=2 mol. STP stands for the standard temperature and pressure which means the temperature is 0 ℃ and pressure is 100 kPa. And the molar volume of gas is 22.7 L/mol under STP. So the answer is 22.7*2=45.4 L
