Does 70 kill bacteria?

Viruses are inactivated at temperatures between 60 °C and 65 °C, but more slowly than bacteria. However, as shown for poliovirus and hepatitis A, as temperatures increase above 70 °C, a greater than 5 log inactivation (99.999% reduction) is achieved in less than 1 minute.

Can you make water boil at 70 C?

Yes, You can make water boil at 70° C. Since, the Water boils at 100° Celsius at level of the sea.
