Answer:
Metals have high melting points thus unlikely to degrade when temperatures increase, they can be fabricated and are cost effective due to availability.
Explanation:
Aluminum is the most abundant in the Earth's crust with good thermal and electric properties. It is soft, malleable ,ductile and lighter making it a vital metal in construction industry. An alloy of copper and tin, bronze is a better connector of heat and electricity ,commonly used in automobile industry for bearings and springs production. Steel a carbon alloy has applications in forging and automotive.
Answer:
Assumption:
1. The kinetic and potential energy changes are negligible
2. The cylinder is well insulated and thus heat transfer is negligible.
3. The thermal energy stored in the cylinder itself is negligible.
4. The process is stated to be reversible
Analysis:
a. This is reversible adiabatic(i.e isentropic) process and thus 
From the refrigerant table A11-A13
sat vapor
m=
b.) We take the content of the cylinder as the sysytem.
This is a closed system since no mass leaves or enters.
Hence, the energy balance for adiabatic closed system can be expressed as:
ΔE
ΔU
![w_{b, out} =m([tex]u_{1} -u_{2](https://tex.z-dn.net/?f=w_%7Bb%2C%20out%7D%20%3Dm%28%5Btex%5Du_%7B1%7D%20-u_%7B2)
)
workdone during the isentropic process
=5.8491(246.82-219.9)
=5.8491(26.91)
=157.3993
=157.4kJ
Answer:
The material with the higher specific heat capacity would cause a more severe burn.
Explanation:
Quantity of heat (Q) = mass of material (m) × specific heat capacity (C) × temperature difference (∆T)
From the formula above, the relationship between Q and C is direct in which increase in one quantity (C) leads to a corresponding increase in the other quantity (Q)
The material with the higher specific heat capacity would produce more heat, thus cause a more severe burn.
Answer:
#include <stdio.h>
void SplitIntoTensOnes(int* tensDigit, int* onesDigit, int DecVal){
*tensDigit = (DecVal / 10) % 10;
*onesDigit = DecVal % 10;
return;
}
int main(void) {
int tensPlace = 0;
int onesPlace = 0;
int userInt = 0;
userInt = 41;
SplitIntoTensOnes(&tensPlace, &onesPlace, userInt);
printf("tensPlace = %d, onesPlace = %d\n", tensPlace, onesPlace);
return 0;
}
