Specific heat is the amount of heat absorb or released by a substance to change the temperature to one degree Celsius. To determine the specific heat, we use the expression for the heat absorbed by the system. Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:
Heat = mC(T2-T1)
By substituting the given values, we can calculate for C which is the specific heat of the material.
2510 J = .158 kg ( 1000 g / 1 kg) (C) ( 61.0 - 32.0 °C)
C = 0.5478 J / g °C
Answer: 149
Explanation:
Using the ideal gas equation; PV = nRT
P= Pressure = 0.910 atm, T= Temperature = ?
V= Volume = 4.0L R = Gas constant = 0.08206 L.atm/mol/K
n = number of moles = 0.297
Making 'T' the subject of the formular, we have;
T = P V/ n R = 0.910 x 4 / 0.297 x 0.08206
= 149
Explanation:
Density = 1.60 g/mL
Initial Temperature T1 = 218.0°C + 273 = 491 K (Upon converting to kelvin temperature)
Final Temperature T2 = 750.0°C + 273 = 1023 K (Upon converting to kelvin temperature)
Mass of gas = 1.00 lb = 453.592 g (Upon converting to g)
Final Volume V2 = ?
Initial volume can be obtained from;
Density = Mass / Volume
Volume = Mass / Density
Volume = 453.592 / 1.60 = 283.495 ml
Initial Volume V1 = 283.495 ml
Using charles law;
V1 / T1 = V2 / T2
V2 = V1 * T2 / T1
V2 = 283.495 * 1023 / 491
V2 = 590.66 ml
Answer:
5f14 6d10 7s2 7p6
Explanation:
This is because oganesson is a noble gas and element of group 18 which does not occur or is not produced naturally. It is produced in an experiment. It is a gas at room temperature and it has atomic number of 118. It is harmful and a radioactive gas due to it's radioactive properties and it is produced in small amound
