The defining equation for calorimetry is __________.

2 answers:

8 0

The science or act of measuring modifications in state variables of a body for the aim of obtaining the heat transfer related to the modifications of its state due is known as calorimetry. The calorimetry is conducted with the help of calorimeter.

Calorimetry is fundamentally the science related to the exchange of heat with the surroundings. Therefore, the defining equation of calorimetry will be ΔQ1 +ΔQ2 = 0.

Answer:

Q=m.c.ΔT

Explanation:

Calorimetry is the part of physics that studies the phenomena related to thermal energy exchanges. This energy in transit is called heat and occurs due to the temperature difference between the bodies.

Calorimetry can be defined by the equation: Q = m.c.ΔT

Q: Sensitive heat amount (J or lime)
m: body mass (kg or g)
c: specific heat (J / kg ° C or cal / g ° C)
ΔT: temperature range (° C), ie final temperature minus initial temperature

An ideal gas is held in a container of volume V at pressure p. The rms speed of a gas molecule under these conditions is v. If n

Answer:

d) 2v

Explanation:

Since, root mean square speed of a molecule,

$V_{rms}=\sqrt{\frac{3kT}{m}}$

Where,

k = Boltzmann constant,

T = temperature of gas,

m = mass of molecule,

Also, the temperature of a gas,

$T=\frac{pV}{nR}$

Where,

p = pressure of the gas,

V = volume,

n = number of moles of gas,

R = universal gas constant,

$\implies V_{rms}=\sqrt{\frac{3kpV}{mnR}}$

If V = 2V and p = 2P

Then,

$V_{rms}=\sqrt{\frac{12kpV}{mnR}$

$=2\sqrt{\frac{3kpV}{mnR}$

Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v

i.e. option d is correct.

Zarrin [17]

Mary might be diagnosed as having a psychological eating disorder called Anorexia Nervosa as well as Bulemia Nervosa which are characterized by extreme weight loss, a fear of gaining weight, and a distorted body image. Bulemia Nervosa involves periods of excessive overeating, called binging, followed by purging, which is forcing one's self to vomit the food that was just eaten. Both conditions are severe and life-threatening and require professional help through counseling, monitoring, medication, and emotional support. Eating disorders can affect anyone, both male and female, of any age, but are most prevalent among American women and are rising in number among college-age women.

If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?

Serggg [28]

Answer: 4 Guanines

Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.

We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
