What is the coldest liquid on Earth?
Liquid helium
Is liquid nitrogen or liquid oxygen colder?
Liquid nitrogen has a lower boiling point at −196 °C (77 K) than oxygen’s −183 °C (90 K), and vessels containing liquid nitrogen can condense oxygen from air: when most of the nitrogen has evaporated from such a vessel, there is a risk that liquid oxygen remaining can react violently with organic material.
What substance is most coldest?
Answer has 19 votes. Liquid hydrogen is the coldest substance known to man, minus 400 degrees.
What is the world’s hottest substance?
By zapping a piece of aluminum with the world’s most powerful x-ray laser, physicists have heated matter to 3.6 million degrees Fahrenheit (2 million degrees Celsius)—making it briefly the hottest thing on Earth. Only locations such as the heart of the sun or the center of a nuclear explosion are hotter.
What is the hottest water in the world?
Answer: The hottest ocean area is in the Persian Gulf, where water temperatures at the surface exceed 90 degrees Fahrenheit in the summer. Another hot area exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6,500 feet.
Which is the coldest gas in the world?
Absolute zero is the coldest. It is -459 F.
Can global warming trigger ice age?
These ice ages are triggered and ended by slow changes in the Earth’s orbit. There is a real risk that, if emissions continue to rise, the world warms more this century than it did between the middle of the last ice age 20,000 years ago and today.
How fast did the ice age happen?
The Earth has been alternating between long ice ages and shorter interglacial periods for around 2.6 million years. For the last million years or so these have been happening roughly every 100,000 years – around 90,000 years of ice age followed by a roughly 10,000 year interglacial warm period.
What was the highest temperature during the ice age?
about 46 degrees Fahrenheit
What happened 12000 years ago?
12,000 years ago: Volcanic eruptions in the Virunga Mountains blocked Lake Kivu outflow into Lake Edward and the Nile system, diverting the water to Lake Tanganyika.
