I think it's because heat denatures the proteins within the phospholipid bilayer of enveloped viruses. This is required to maintain the integrity of virions in enveloped viruses.
For some reason, I think it's harder to denature proteins within the capsid, so naked viruses are less susceptible to heat treatment.
Sorry it's not a very clear answer.

...but it's a good answer it sounds like a paradox, but encapsulated viruses ARE more sensitive to environmental factors than the naked ones. for the reason above (Moc's explanation) ___________________ There are 3 types of people: those who make things happen, those who watch things happen, and those who wonder what happened.

Above is correct, but i think spores are more resistant than the other two.

Hi guy, but the question ask for heat sensitivity, not for resistance

Oops...you're right...then based on the above explanation enveloped viruse are the most sensitive.
