In what way would readings from a digital thermometer be preferable to those from a liquid-based thermometer?

Answers

Answer 1

Answer:

A digital thermometer is more preferable than a liquid-based thermometer because it gives accurate data than the liquid thermometer. Liquid thermometer is affected by the temperature, and when it does, the liquid expands and so des the material covering the thermometer. For the digital thermometer, it has less error because it already has a sensor inside it that determines the temperature of the substance.

A 34.87 g sample of a substance is initially at 27.1 C. after absorbing 1071 J of heat, the temperature of the substance is 145.0 C. what is the specific heat (SH) of the substance?SH=___ J / g * C

Answers

$H= (1071)/(34.87)*145\nH= (155295)/(34.87) \nH= (15529500)/(3487) \nH=4453.542$

Answer: .1044 J/g*C°

Explanation: The equation you need to use for this problem is :

c= q/m* ΔT

We are given

T1= 27.1 C°

T2= 145 C°

M= 34.87g

1071 J absorbed heatt

So let's solve specific heat

c= 1071J/ (87grams)*(145 C°- 27.1 C°)

c= 1071J/10,257.3 g*C°

c= .1044 J/g*C°

c=specific heat

Ionic bonds result from high electronegativity differences.
a. True
b. False

Answers

Answer: True

Explanation: An ionic bond is formed when an element completely transfers its valence electron to another element.

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element.

This bond is formed between a electropositive metal $M^+$ and a electronegative non-metal $X^-$ .

Final answer:

Ionic bonds result from high electronegativity differences. True.

Explanation:

Ionic bonds result from high electronegativity differences. True. An ionic bond is formed when one atom, usually a metal, transfers one or more electrons to another atom, typically a nonmetal, resulting in the formation of ions with opposite charges. Electronegativity is the tendency of an atom to attract a shared pair of electrons in a covalent bond. When there is a high electronegativity difference between two atoms, one atom will strip electrons away from the other, leading to the formation of ionic bonds.

A gas of 190 mL at a pressure of 74 atm can be expected to change its pressure when its volume changes to 30.0 mL. Express its new pressure in units of atmospheres.

Answers

Answer : The new pressure of the gas will be, 468.66 atm

Explanation :

Boyle's Law : This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto (1)/(V)$ (At constant temperature and number of moles)

or,

$P_1V_1=P_2V_2$

where,

$P_1$ = initial pressure of the gas = 74 atm

$P_2$ = final pressure of the gas = ?

$V_1$ = initial volume of the gas = 190 ml

$V_2$ = final volume of the gas = 30 ml

Now we put all the given values in the above formula, we get the final or new pressure of the gas.

$74atm* 190ml=P_2* 30ml$

$P_2=468.66atm$

Therefore, the new pressure of the gas will be, 468.66 atm

Answer: The new pressure of the gas is 467 atm.

Explanation:

To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$

where,

$P_1\text{ and }V_1$ are initial pressure and volume.
