Answer:
LDPE would be the best choice for a hand warmer designed to release heat quickly.
Explanation:
Judging from the graph, the LDPE plastic releases heat quicker than the Latex. (and I also did the gizmo-)
Explanation:
The answer is 116 kJ . c - water's specific heat - 4.184 J/g⋅∘C . Then, you must provide enough heat to get all the water from liquid to steam.
I pretty sure the answer is true but here is also a site to help you. https://www.britannica.com/science/wave-water
Answer:
580mmHg
Explanation:
Given parameters:
Number of moles = 0.884 mol
Temperature = 6°C = 273 + 6 = 279k
Volume = 26.5L
Unknown:
Pressure = ?
Solution:
To solve this problem, we use the ideal gas equation:
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
P = = = 0.76atm
1 atm = 760mmHg
0.76 atm = 760 x 0.76 = 580mmHg
