Answer:
the average kinetic energy of a system
Explanation:
the more kinetic energy in something, the hotter it is, the less kinetic energy in something, the cooler it is. gases have the most kinetic energy. solids have the least, but everything has kinetic energy
Answer:
Selling puffs and juuls right now. I have strawberry and mint i'm almost out of stalk hurry and buy one for just 1$ alone or you can get 2 juuls with a candy bag depending on how much candy or juuls you buy.
Explanation:
Answer:
<u><em>=355.5K</em></u>
Explanation:
Specific heat, Q = mcΔT
where
- Q= 4250J
- ΔT= change in temp = final temp - initial temp
- c = specific heat capacity = 1.7
- m = mass of substance in grams
[1 mole of Ne = 20g; 2 moles of Ne = 2 × 20 = 40g]
4250 = 40 × 1.7 × (final - 293K)
final - 293k = 4250 / ( 40 × 1.7)
Final temp = 62.5 + 293
<em>=355.5K</em>
I hope this steps are simple to follow and understand.
Answer: The final temperature of both substances at thermal equilibrium is 301.0 K
Explanation:
As we know that,
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%3D-%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
.................(1)
where,
q = heat absorbed or released
= mass of gold = 31.5 g
= mass of water = 63.4 g
= final temperature = ?
= temperature of gold = 
= temperature of water = 
= specific heat of gold = 
= specific heat of water= 
Now put all the given values in equation (1), we get
![-31.5\times 0.129\times (T_{final}-342.4)=[63.4\times 4.184\times (T_{final}-300.4)]](https://tex.z-dn.net/?f=-31.5%5Ctimes%200.129%5Ctimes%20%28T_%7Bfinal%7D-342.4%29%3D%5B63.4%5Ctimes%204.184%5Ctimes%20%28T_%7Bfinal%7D-300.4%29%5D)
The final temperature of both substances at thermal equilibrium is 301.0 K
