How did the industrial revolution motivate europe to colonize and expand?

First of all the industrial revolution motivated Europe to colonize for economic reasons. But by two different motives: wealth production and power over their enemies.

Explanation:

The industrial revolution allowed the European powers to develop technology to acquire wealth and advantage over their enemies and because they conquered each other for the wealth they realized they had found a better way to gain wealth and power over their enemies. So, they started a race of production to empower themselves and avoid being attacked. That guided them to discover a huge need for raw materials that could be found in unconquered territories and they decided to expand and colonize.
