English question: Are there any cases that Be Subject To and Be Subjected To are interchangeable each other.?

From my grammar context, I kind of know that some regulations related to this two terms are as follows.

Typical uses:

Be Subjected To

(A) phrasal verb: subject somebody/something to something

Oxford - [often passive] to make somebody/something experience, suffer or be affected by something, usually something unpleasant (there is an implied actor of the verb)

Be Subject To

(B1) adjective:

- be subject to something (likely to be affected by something, especially something bad)

(B2) adjective:

- be subject to a rule/law/penalty/tax etc.

My second question is: Are the following sentences correct in using “Be Subject To” or “Be Subjected To”

1. Offenders who rape girls under 12 may now be subject to (reason– B2) the death penalty in India, according to an ordinance passed by India’s cabinet Saturday after a nationwide furor over the rape and killing of an 8-year-old girl.

2. Loan sharks are a blight on society and prey on vulnerable people who struggle to make ends meet. These criminals use callous methods to enforce repayment and victims are often subjected (reason -- A) to threats, intimidation and violence.

3. A silver bar 0.125 meter long is subjected to (Reason – I don’t know, please help) a temperature change from 200°C to 100°C.?

I’m an English learner and your help will be much appreciated.

Thank you very much.
