Blisters can occur in 5 seconds in water if the temperature is 140° Fahrenheit (60° Celsius). 120 degrees and below is considered safe. Between 121-140 degrees may cause blistering, but depends on skin type and age of person.
Based on the results of a study published in 1953 titled "BLISTER FORMATION AND TISSUE TEMPERATURE IN RADIANT ENERGY AND CONTACT BURNS" I would estimate that a temperature around 160o F would cause a burn.
In their experiments, Sprague-Dawley albino rats' (and also pigs') ears were used as the subject of testing, and for 0.25 second exposures to hot water, 71o C (~160o F) was enough to cause blistering.
One interesting part of the experiment was the measurement of subcutaneous skin temperature measured about 0.5mm under the skin. The temperature there would rise after exposure, peaking about 5 seconds after exposure.
The lesson here is that if you burn yourself, try to rinse the affected part under cold water and try to remove the heat as it tries to conduct itself into your skin. If you are able to reduce the temperature within 5 seconds, you might be able to avoid a blister.

A second degree burn causes blistering.
Signs of a burn are localized redness, swelling, and pain. A severe burn will also blister.
No
No it will not.
A blister has clear fluid under the skin, and a blood blister has blood under the skin. If it's a burn, it's most likely a blister.
an iron burn can cause wound which requires air to heal
You get a blister, it depends how deep the burn is.
Usually a blister or acne is this. Though it also is usually a burn that causes it.
You leave it alone. Do not break the blister because the skin is repairing underneath.
bake, burn, blister, melt, cook, roast
Because your lips get wind burn
You may put a thin layer of ointment like aloe vera after your blister has broken and is running.
