Will a microwave explode? The water in their body heats up due to molecular resonance with the microwaves. Their eyeballs may explode from the pressure build-up as the water in them turns to steam with nowhere to escape. After a few minutes the heat will have penetrated deep into their bodies, causing their internal organs […]

What is the lowest temperature that a substance can reach? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. What is 70 […]
