10 Lessons in Chapter 3: Temperature & Heat in Engineering
Ambient Temperature: Definition & Range

1. Ambient Temperature: Definition & Range

In this lesson, you will learn that ambient temperature can be interpreted in more than one way. You will also learn the range of temperatures that can be defined as ambient temperature in different situations.

How to Read Time Temperature Transformation Diagrams

2. How to Read Time Temperature Transformation Diagrams

This lesson defines the terms phase and microstructure, introduces time temperature transformation diagrams, and explains how these diagrams can be used to predict the phases and microstructures present in a material.

Air Cooled Heat Exchanger: Definition & Design

3. Air Cooled Heat Exchanger: Definition & Design

This lesson describes the working principle and design of an air cooled heat exchanger. The fundamental heat transfer equation used for an air-cooled heat exchanger is described and is used to explain the design methodology for designing an air-cooled heat exchanger.

Sensible Cooling: Definition & Load

4. Sensible Cooling: Definition & Load

Sensible Cooling Load is one of the two types of cooling loads that comprise the design cooling load. This article describes what sensible cooling load is, how it is different from latent cooling load and how these calculations are used to calculate the design cooling load of HVAC systems.

Sensible Heat: Definition, Load & Equation

5. Sensible Heat: Definition, Load & Equation

Sensible heat is the amount of thermal energy that is required to change the temperature of an object. This lesson will look at how sensible heat changes that temperature and the equation that we use to model the temperature change.

Sensible vs. Latent Heat

6. Sensible vs. Latent Heat

In this lesson, the conceptual difference between sensible and latent heat is discussed. Sensible heat is heat that can be measured on a thermometer, while latent heat is the type of heat energy that allows for phase changes, such as those between liquid and gas forms of a substance.

Absolute Humidity: Definition & Equation

7. Absolute Humidity: Definition & Equation

Absolute humidity is the mass of water vapor divided by the mass of dry air in a certain volume of air at a specific temperature. The warmer the air is, the more water it can absorb.Absolute humidity is the measure of water vapor or moisture in the air, regardless of temperature.

Absolute Humidity vs. Relative Humidity: Formulas & Conversion

8. Absolute Humidity vs. Relative Humidity: Formulas & Conversion

In this lesson, you will learn the difference between absolute humidity and relative humidity. You will understand how humidity (or moisture content) relates to the composition of air, and the relationship between different ways of representing the humidity level of air.

Thermal Expansion and Contraction

9. Thermal Expansion and Contraction

In this lesson, you'll learn how materials change when temperature changes. You'll also explore how this change is measured and how the coefficient of thermal expansion helps measure this change.

Thermal Gradient: Definition & Calculation

10. Thermal Gradient: Definition & Calculation

This lesson defines a quantity called the thermal gradient and describes how to calculate it. The importance of thermal gradients in the field of thermal engineering along with an example is also included here.
