The definition of calorie should be determined along with the difference between Calorie and calorie and relation of joule with calorie. The definition of specific heat capacity should be discussed and identify the substance having relatively high specific heat capacity, which makes it useful for cooling. Concept Introduction: Joule, calorie and Calorie (kilocalorie) are the units of energy and S.I unit of energy is Joule. The symbol of joule is J, calorie is cal and Calorie is Cal or kcal. A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.

Question

need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).

Question

Chapter 12, Problem 5CR

Interpretation Introduction

Interpretation:

The definition of calorie should be determined along with the difference between Calorie and calorie and relation of joule with calorie. The definition of specific heat capacity should be discussed and identify the substance having relatively high specific heat capacity, which makes it useful for cooling.

Concept Introduction:

Joule, calorie and Calorie (kilocalorie) are the units of energy and S.I unit of energy is Joule.

The symbol of joule is J, calorie is cal and Calorie is Cal or kcal.

A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
